Overview
The TPIC2810D, produced by Texas Instruments, is a monolithic, medium-voltage, low-current, 8-bit shift register designed to drive low-side switched resistive loads such as LEDs. This device is not recommended for switching inductive loads. It features an I2C bus interface for data transfer and control, making it suitable for various applications requiring precise LED control.
The device includes an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. It has internal power-up clear and thermal shutdown mechanisms to ensure safe operation. The TPIC2810D is characterized for operation over a wide temperature range of −40°C to 125°C.
