TPIC2810D

Overview

The TPIC2810D is a monolithic, medium-voltage, low-current, 8-bit shift register designed to drive low-side switched resistive loads such as LEDs. It features an I2C interface for control and operates with a supply voltage range of 3 V to 5.5 V. The device provides an output voltage capability of 40 V and delivers a low-level output current of 100 mA per channel. It supports a maximum frequency of 2 MHz and functions within a junction temperature range of -40°C to 150°C. The component is housed in a 16-SOIC package.

Feature Summary

• Integrates an I2C interface for simplified serial control of the 8-bit shift register.
• Designed specifically for driving low-side switched resistive loads like LEDs.
• Features internal switches for direct load connection without external components.

Applications

• LED lighting driver circuits
• Resistive load switching applications
• Low-side switched LED arrays

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-16 package variant when ordering. Confirm that the design requires an I2C-compatible master controller. Ensure the application voltage does not exceed the 40 V output rating. Check that the operating temperature range meets the system's thermal requirements. Validate power supply stability within the 3 V to 5.5 V input range.

Selection Notes

Select this component when an I2C-controlled, low-side LED driver is required. It is suitable for designs needing 8 independent channels with moderate current capabilities. Consider the 16-SOIC package for surface-mount assembly constraints. Evaluate the 40 V output voltage headroom against the load requirements. Ensure the system architecture supports the 2 MHz interface speed.

Part Context

The TPIC2810D belongs to Texas Instruments' family of LED drivers and shift registers. It is part of the broader TPIC series, which offers various configurations for lighting control. The device serves as a bridge between digital controllers and analog loads, simplifying PCB layout by integrating level shifting and protection features into a single monolithic structure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing I2C bus protocols if considering alternative manufacturers. Ensure pinout and electrical characteristics match before substituting any other 8-bit shift register devices.
