Overview

The TPS1HB16BQPWPRQ1 is a single-channel smart high-side switch designed for 12V automotive systems. It features a low 16mOhm Rds(on) and provides robust protection and diagnostic features, including adjustable current limiting and real-time analog current sensing. This AEC-Q100 qualified device is engineered to drive high-current resistive, capacitive, or inductive loads safely.

Why Choose This Part

This device offers a high 49A output current capacity and integrated reverse battery protection, reducing external component count. Its adjustable current limit allows designers to optimize protection for specific wire gauges, while the analog SNS pin provides high-accuracy current monitoring and fault diagnostics.

Applications

Automotive Body Electronics
Driving lighting, seat heaters, and interior fans where high-side switching and fault protection are required.
Inductive Load Driving
Managing solenoids and actuators with integrated output clamps for safe demagnetization.
Smart Power Distribution
Replacing traditional fuses with programmable current limiting and fault reporting in vehicle power modules.
ADCU Power Supply
Providing protected power rails to sensitive automotive control units with functional safety capability.
