Product Description

Infineon BSP76E6433HUMA1 is a low-side power switch integrated circuit in a compact 4-pin SOT-223 surface-mount package designed for efficient switching and protection in electronic systems.

With a power rating of 3.8W and an operating current of 1.4A, this power switch IC is optimized to handle moderate load currents while maintaining low conduction losses thanks to its 480mΩ switch on resistance (Rds(on)).

It supports a wide supply voltage range up to 10V and operates reliably within the temperature range of -40°C to 150°C, making it suitable for harsh environmental conditions and rugged electronics.

The device implements a low-side switching topology, meaning it switches the connection of the load to ground, best placed in series between the load and the return path on the PCB.

This IC accepts a single control input and provides five independent switched outputs for distributing one control signal across multiple loads, making it ideal for centralized load distribution in control modules and systems.

The compact SOT-223 package simplifies PCB design and assembly while providing good thermal performance; designers are advised to use thermal land and copper pours beneath the package pad to aid heat dissipation.

Implements low-side topology for load switching. Supports 1.4A operating current and 3.8W power dissipation. 480mΩ low Rds(on) minimizes conduction loss. Wide temperature tolerance from -40°C to 150°C. Compact 4-pin SOT-223 package for surface mounting.

Provides five independent outputs from one input control signal. Suitable for resistive and small inductive load switching. Designed for applications in automotive and industrial electronics. Requires PCB thermal management for optimal performance.

This Infineon Power Switch IC is ideal for industrial, automotive, and commercial electronics requiring reliable load switching in compact, low-voltage systems.
