Introduction
If you are designing an air conditioner control panel, a set-top box display, or a washing machine interface, chances are you are searching for the TM1650 LED driver IC. This chip from Titan Micro Electronics is one of the most widely used display drivers in the home appliance industry, and procurement teams across India, Southeast Asia, and the Middle East regularly search for a reliable TM1650 supplier that can deliver original chips with proper documentation and competitive pricing.
Finding a dependable TM1650 IC supplier matters more than you might think. A single batch of counterfeit or relabeled chips can cause field failures, display flickering, or keyboard scan errors that damage your product reputation. Whether you need 500 pieces for a pilot run or 50,000 units for mass production, working with the right distributor ensures you get genuine Titan Micro parts, consistent quality, and the technical support to integrate them correctly.
In this guide, we cover everything a buyer or engineer needs to know about sourcing the TM1650 — from technical specifications and application scenarios to supplier selection criteria and pricing considerations. If you need TM1650 stock now, you can contact Newfly Electronics directly for a quotation.
TM1650 Product Overview
The TM1650 is an LED display driver IC with built-in keyboard scan functionality, designed and manufactured by Titan Micro Electronics (天微电子), a leading Chinese semiconductor company specializing in display driver chips. The TM1650 is engineered to drive 4-digit LED displays while simultaneously scanning a matrix keyboard, making it ideal for compact appliance control panels where both display output and user input are required.
Unlike generic LED drivers, the TM1650 integrates two critical functions into a single chip: display driving and key scanning. This dual-function capability reduces component count, saves PCB space, and simplifies circuit design — which is why so many appliance manufacturers in India, Vietnam, and Thailand standardize on this part.
Key features of the TM1650 include:
- 8-segment x 4-bit display mode (or 7-segment x 4-bit)
- Built-in keyboard scan circuit for 4×4 or smaller key matrices
- 2-wire serial interface (CLK, DIO) — MCU-friendly protocol
- Wide operating voltage: 2.8V to 5.5V
- 8-level brightness adjustment via software control
- Available in SOP16 and DIP16 packages
- Low standby current, suitable for battery-powered and low-power designs

Applications and Use Cases
The TM1650 is deployed across a wide range of consumer and industrial products. Its combination of display driving and keyboard scanning makes it a go-to choice for any device that needs a digital readout plus user button input. Here are the most common applications we see from our overseas customers:
Home Appliances: Air conditioner indoor units use the TM1650 to drive the temperature display and scan the mode, fan speed, and timer buttons. Washing machine control panels rely on it for cycle countdown displays and button input. Microwave ovens use it for time and power level display. Set-top boxes in the Indian market frequently incorporate the TM1650 for channel number display and front-panel button scanning.
Industrial Control Panels: Factory equipment HMIs, temperature controller panels, and process measurement instruments use the TM1650 for its reliability in harsh environments. Malaysian electronics manufacturers building industrial timers and counters specify this part for its wide voltage range and stable performance.
Consumer Electronics: Digital clocks, electronic scales, kitchen timers, and small household devices benefit from the TM1650 low pin count and simple 2-wire interface. Vietnamese OEMs producing affordable consumer gadgets frequently select this chip to keep BOM costs low while maintaining display quality.
Arduino and Maker Projects: While not the primary market, many engineers prototype with TM1650-based display modules available on the maker ecosystem. If you are moving from prototype to production and need reliable supply of genuine TM1650 chips, Newfly Electronics can support both small prototype quantities and production volumes.

TM1650 Buying Guide: How to Choose a Reliable Supplier
Selecting the right TM1650 IC supplier is a decision that directly impacts your product quality, production schedule, and cost structure. Here are the critical factors to evaluate when sourcing TM1650 chips from China:
1. Original Source Verification: The market contains relabeled and counterfeit TM1650 chips. A reliable supplier must be able to trace chips back to Titan Micro Electronics. Ask for lot codes, date codes, and packaging labels. Newfly Electronics sources directly from Titan Micro authorized channels and provides full traceability documentation on request.
2. Supply Stability: Can your supplier maintain consistent inventory across production cycles? Many small traders stock a few hundred pieces and run out within weeks. A serious distributor maintains buffer stock and has scheduled replenishment agreements. Verify that your supplier can support your projected annual volume, not just a one-time order.
3. Quality Inspection: Does the supplier perform incoming quality control? At minimum, chips should be visually inspected for marking quality, lead condition, and package integrity. For critical applications, functional testing on a sample basis is recommended. Newfly Electronics performs visual and electrical inspection on every batch before shipping.
4. Export Experience: Shipping ICs from China to India, Vietnam, Thailand, or Europe requires proper documentation, reliable logistics partners, and experience with customs procedures. A supplier with export expertise ensures your shipment arrives on time without customs delays. Newfly Electronics has shipped to over 20 countries and handles all export documentation.
5. MOQ Flexibility: During the prototyping phase, you may need only 100 or 500 pieces. During mass production, you may need 50,000 units. Your supplier should support both ends of the spectrum without excessive price penalties. Newfly Electronics supports small quantity orders for engineering samples and offers volume pricing for production runs.
6. Technical Support: Can your supplier help with register configuration, dimming control, or interface timing questions? A distributor with engineering knowledge adds significant value beyond the transaction. Newfly Electronics provides datasheets, application notes, and engineering support for all Titan Micro ICs we supply.
TM1650 Price and Stock Availability
Pricing for the TM1650 varies based on package type (SOP16 vs DIP16), order quantity, and current market conditions. As a Titan Micro distributor, Newfly Electronics offers pricing that is typically 10-20% below what overseas buyers receive when approaching the original factory directly — because Titan Micro does not maintain a dedicated foreign trade sales team and quotes premium prices to international inquiries.
Current TM1650 stock is available in both SOP16 and DIP16 packages. For an exact quotation based on your required quantity and package type, please contact us at sales@newflyelectronics.com or message us on WhatsApp at +86 15112635657. We respond to all quotation requests within 24 hours.
Factors that affect TM1650 pricing include:
- Package type: SOP16 (surface mount) is generally lower cost than DIP16 (through-hole)
- Order volume: pricing steps down significantly at 1K, 5K, and 10K piece quantities
- Tape and reel packaging for automated assembly: adds small cost but required for SMT lines
- Shipping method and destination: affects landed cost
