TPL9202PWPR

Sensor And Detector Interfaces Overview

The TPL9202PWPR 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 (LDO) regulator to supply power to the control logic and external components. The device operates within a supply voltage range of 7 V to 18 V and delivers a peak output current of 150 mA per channel. It supports CMOS logic inputs and functions across a temperature range of -40°C to +125°C. Key electrical parameters include a maximum power dissipation of 3.787 W and a typical operating supply current of 5 mA.

Sensor And Detector Interfaces Feature Summary

• Integrates an internal 5V LDO regulator for simplified system design
• Provides eight independent low-side drive channels for relay control
• Supports high-temperature operation up to 125°C for industrial environments

Sensor And Detector Interfaces Applications

• Industrial automation systems requiring multi-channel relay switching
• Automotive body control modules and lighting applications
• Consumer appliances with multiple electromechanical loads

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure that the selected variant matches the required thermal performance and moisture sensitivity level for the intended manufacturing process. Cross-reference the datasheet revision date to confirm compatibility with current design standards.

Sensor And Detector Interfaces Selection Notes

Select this component when a compact solution for driving multiple relays from a single IC is required. The integrated 5V LDO eliminates the need for an external voltage regulator, reducing board space. Consider the 150 mA per-channel current limit to ensure it meets the coil requirements of the target relays without exceeding thermal limits.

Sensor And Detector Interfaces Part Context

The TPL9202 belongs to the TPL920x family of relay drivers designed for high-density applications. It serves as a direct interface between microcontrollers or logic circuits and electromechanical relays. The series is characterized by its integration of regulation and protection features within a small form factor suitable for space-constrained designs.

Sensor And Detector Interfaces Replacement Considerations

Consult official substitution guides for compatible devices within the same product family. Verify pin-to-pin compatibility and electrical parameter alignment before replacing existing inventory.
