TPL9202PWPG4

Overview

The TPL9202PWPG4 is an eight-channel low-side relay driver manufactured by Texas Instruments, housed in a 20-pin HTSSOP package. It integrates an internal 5V Low Dropout Regulator (LDO) to supply power for the internal logic and output stages. The device operates within a supply voltage range of 7 V to 18 V and supports a maximum output current of 150 mA per channel. Designed for CMOS logic compatibility, it functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates an internal 5V LDO regulator to simplify external power requirements
• Provides eight independent low-side drive channels for relay control
• Compatible with standard CMOS logic input levels

Applications

• Automotive body control modules requiring multiple relay switching
• Industrial equipment with high-density I/O relay interfaces
• Consumer appliances utilizing solid-state or electromechanical relay arrays

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as defined by Texas Instruments. Confirm the HTSSOP-20 package dimensions match the design footprint. Ensure the operating environment stays within the specified -40°C to +125°C thermal limits to maintain reliability.

Selection Notes

Select this component when eight isolated low-side outputs are required with integrated logic power regulation. Compare against the TPIC9202 series if higher current capabilities or different packaging options are needed. Verify that the 150 mA per channel limit meets the load requirements of the target relays.

Part Context

This part belongs to the TPL9202 family of microcontroller power supplies and multiple low-side drivers. It serves as a specialized interface between digital controllers and high-current loads, distinct from general-purpose gate drivers by its integrated LDO and multi-channel architecture optimized for relay applications.

Replacement Considerations

The TPIC9202 series offers similar functionality but may differ in current ratings or pinout configurations. Verify electrical parameters and mechanical dimensions before substitution. Consult official datasheets for both components to ensure compatibility with existing circuit designs.
