Infineon Low Side Powertrain Switch Power Switch IC 5V 5A 4 Outputs Serial Interface PG-DSO-20 TLE9104SHXUMA1

Infineon TLE9104SHXUMA1 Low Side Powertrain Switch Power Switch IC is designed for automotive electrical control, providing reliable and efficient switching of loads in powertrain systems. This low-side switch operates with a supply voltage from 3V to 5V and supports an operating current up to 5 amperes per channel, featuring four independently controlled outputs. The device is housed in a compact PG-DSO-20 surface-mount package with 20 pins, ideal for high-density automotive electronic assemblies.

The switch topology implemented is low-side, which connects the load to ground when activated, suitable for driving resistive and inductive loads. It utilizes a serial interface to allow system-level integration and seamless command control, typically via CAN or ECU networks found in modern vehicles. Its design meets the rigorous automotive standards AEC-Q101 and AEC-Q100, ensuring high reliability under thermal stress ranging from -40°C to 150°C.

This power switch IC features a low on-resistance of 150 milliohms, reducing conduction losses and improving system efficiency. Each of the four outputs can be independently controlled, providing flexibility for multiplexed actuator switching in complex vehicle subsystems such as lighting and motor driver applications.

The device includes four independent output channels for flexible control. It supports up to 5 amperes operating current per channel. Low on-resistance of 150mΩ optimizes power efficiency. Designed to operate in extreme temperatures from -40°C to 150°C.

Meets automotive AEC-Q101 and AEC-Q100 certification standards. Compact PG-DSO-20 package with 20 pins enhances board layout. Serial interface simplifies integration with vehicle control units. Compatible with CAN and ECU for networked automotive control.

This Power Switch IC is well-suited for automotive, industrial, and manufacturing applications where robust, reliable load switching is necessary. Its surface-mount form factor enables easy integration on compact PCBs used in modern vehicle electronics. Suitable use cases include controlling lighting systems, actuators, and motor drivers in harsh vehicular environments.
