TM1628 IC Supplier China | Datasheet & Stock

/ Titan Micro IC / By









Introduction

The TM1628 is a dedicated LED display driver IC with built-in keyboard scanning functionality, designed and manufactured by Titan Micro Electronics (天微电子). For electronics manufacturers producing home appliances such as air conditioner control panels, washing machines, and microwave ovens, the TM1628 is a critical component that drives both the display interface and user input processing. When production schedules demand consistent supply and engineers need reliable technical documentation, finding a dependable TM1628 IC supplier becomes a purchasing priority.

Overseas manufacturers in India, Vietnam, Thailand, Malaysia, and other emerging electronics production hubs frequently search for TM1628 suppliers that can offer competitive pricing, stable stock, and export-ready service. Titan Micro Electronics does not maintain a dedicated foreign trade sales team, which means overseas buyers often face high quoted prices and communication barriers when sourcing directly. This is where Newfly Electronics steps in as a China-based distributor with deep expertise in Titan Micro IC products.

TM1628 Product Overview

The TM1628 is an LED display driver IC that integrates display driving and keyboard scanning into a single chip. Manufactured by Titan Micro Electronics, it is specifically engineered for appliance control panel applications where both visual output and user input are required on the same module.

Manufacturer: Titan Micro Electronics (天微电子)

Primary Function: LED display driver with keyboard scan interface

Key Features:

  • 10-segment x 7-bit to 13-segment x 4-bit display driving capability
  • Built-in keyboard scanning circuit (up to 10 x 2 matrix)
  • 3-wire serial interface (DIN, CLK, STB) for MCU communication
  • 8-level brightness adjustment via software control
  • Integrated RC oscillator, no external clock required
  • Automatic display refresh, reducing MCU workload
  • SOP28 surface-mount package for compact PCB design

The TM1628 simplifies appliance control panel design by combining display driving and key scanning into one IC. This reduces component count, saves PCB space, and lowers overall BOM cost compared to using separate driver and scanning circuits. Engineers designing air conditioner panels, washing machine interfaces, and microwave oven controls benefit from the TM1628’s integrated approach.

Applications and Use Cases

The TM1628 is widely used in home appliance control panels where LED digital displays and button inputs coexist. Its integrated keyboard scanning feature makes it particularly valuable for applications that require both display output and user interaction on a single PCB.

Air Conditioner Control Panels: The TM1628 drives the temperature display, mode indicators, and timer readout while scanning the user input buttons for mode selection, fan speed, and temperature adjustment. Air conditioner manufacturers in India and Vietnam commonly design the TM1628 into their indoor unit control boards.

Washing Machine Displays: Washing machine control panels use the TM1628 to show wash cycle status, remaining time, and error codes. The keyboard scan function handles cycle selection, start/stop, and option toggle inputs. Manufacturers in Thailand and Malaysia integrate the TM1628 into both top-load and front-load washing machine designs.

Microwave Oven Interfaces: Microwave oven control panels require digit displays for cooking time and power level, plus key inputs for function selection. The TM1628’s combined display and scan capabilities make it a natural fit for this application. Electronics manufacturers in the Philippines and Indonesia frequently specify the TM1628 in microwave oven designs.

Industrial Control Panels: Beyond consumer appliances, the TM1628 is used in industrial equipment displays that require simple numeric readouts and button-based user interfaces. Factory automation equipment, measurement instruments, and process control displays benefit from the TM1628’s reliable operation and straightforward MCU interface.

Consumer Electronics: The TM1628 also appears in digital clocks, timer modules, and other consumer electronics products that need segmented LED displays with user input. Its SOP28 package and 3-wire interface keep designs compact and cost-effective.

Buying Guide: How to Choose a TM1628 Supplier

Selecting the right TM1628 IC supplier is critical for maintaining production continuity and controlling costs. When evaluating potential suppliers for the TM1628, consider the following factors:

1. Original Source Verification
Ensure the supplier provides genuine Titan Micro Electronics (天微电子) TM1628 ICs. Counterfeit or remark chips are a significant risk in the gray market. Request traceability documentation, lot codes, and original packaging photos. Newfly Electronics sources directly from Titan Micro authorized channels and provides full traceability for every shipment.

2. Supply Stability and Stock Availability
A reliable TM1628 supplier should maintain consistent stock levels and provide accurate lead time information. Ask about typical stock quantities, restock cycles, and the supplier’s ability to handle quantity surges. Newfly Electronics maintains regular TM1628 inventory and can scale orders from small batches to bulk quantities.

3. Quality Inspection and Testing
The supplier should have quality control processes in place, including incoming inspection, visual verification, and functional testing. Request information about the supplier’s QC procedures and whether they provide test reports. Newfly Electronics performs visual and functional inspection on all TM1628 shipments before export.

4. Export Experience and Documentation
For overseas buyers, the supplier’s export experience matters. The supplier should provide proper commercial invoices, packing lists, COO (Certificate of Origin), and comply with international shipping requirements. Newfly Electronics has extensive experience exporting IC components to India, Southeast Asia, the Middle East, Europe, and the Americas.

5. MOQ Flexibility
Different production stages require different quantities. During prototyping, you may need just a few pieces; during mass production, you need thousands. A good TM1628 supplier accommodates both small and large orders without excessive price penalties. Newfly Electronics supports orders from small quantities for R&D to bulk orders for mass production.

6. Pricing Competitiveness
Titan Micro Electronics quotes high prices to overseas buyers due to the lack of a dedicated foreign trade team. A China-based distributor like Newfly Electronics leverages domestic supply chain advantages to offer significantly more competitive pricing while maintaining original product quality.

7. Technical Support
The supplier should be able to provide datasheets, application notes, and basic technical support. This is especially important for engineers integrating the TM1628 into new designs. Newfly Electronics provides datasheets, pinout information, and application guidance to help your engineering team succeed.
