Product Description:
The TM1818 is a serial-interfaced LED driver IC that provides constant current to 16 LED clusters, ensuring uniform intensity for LED displays. The output current can be precisely controlled using an external resistor, with a range from 5mA to 60mA. The TM1818 can handle a maximum voltage of 17V DC on each output, making it a reliable solution for driving LED displays. Its integrated shift registers and data latches allow for efficient control of the LEDs. The serial data input rate can reach up to 25MHz, making the TM1818 ideal for high-volume data transmission in applications that require rapid control of large LED displays.
Key Features:
- 16 Constant-Current Outputs: Each output can drive up to 17V with constant current regulation.
- Precise Current Control: Output current range from 5mA to 60mA, with ±1.5% current matching between outputs and ±2.0% current matching between ICs.
- Single External Resistor: Current output values are programmed using one external resistor, simplifying design and setup.
- High-Speed Data Transfer: Supports serial data transfer rates up to 25MHz, ensuring fast communication for large displays.
- Operating Voltage: Suitable for 3.5V to 4.5V supply voltage range.
- Package Options: Available in SOP24, SSOP24, and QSOP24 packages.
