Infineon High Side Power Switch IC 40V Maximum Supply Voltage 0.2Ω RdsOn 1.8W Power Rating 4-Pin SOT-223 BSP452HUMA1

Infineon BSP452HUMA1 High Side Power Switch IC is designed for automotive electronic systems requiring controlled high-side switching with robust 40V maximum supply voltage tolerance. This power switch IC features a low 0.2 Ω on-resistance, significantly reducing conduction losses and improving overall system efficiency. With a power rating of 1.8W and low quiescent current of 1.6mA, it supports moderate continuous dissipation while keeping standby power consumption minimal.

The device operates reliably over a broad automotive temperature range from -40°C up to 150°C, suitable for use under vehicle bonnet conditions. It accepts one control input and distributes switching across five separate outputs, enabling centralized control of multiple loads such as lighting modules, sensor clusters, and body electronics circuits.

The BSP452HUMA1 comes in a compact 4-pin SOT-223 surface-mount package with dimensions 6.5 x 3.5 mm and a 1.6 mm height, simplifying automated PCB assembly processes. Its high-side power switch topology offers switched positive supply control, ideal for auxiliary power circuits within automotive environments, compliant with AEC standards.

Applications include power distribution for lighting modules, load switching in body electronics, sensor cluster power management, and auxiliary power control. Its rugged design also ensures suitability in commercial and industrial automotive electronic manufacturing and repair sectors.
