Infineon HITFET Series Power Switch IC, 350mA Operating Current, 1.9Ω Switch On Resistance - BTS3405GXUMA1

This power switch IC is a smart low-side MOSFET device designed for automotive control tasks, providing multiple switched outputs for vehicle systems. It is intended for use in environments requiring vehicle-grade operation and integrates control logic with power switching to manage low-side loads from a single package. The component is supplied in a compact eight-pin SOIC surface-mount package suitable for board-level integration in automotive electronic modules.

Features and Benefits:

• Five independent outputs offering multi-load control and simplified harnessing
• 350mA operating current supporting small actuator and lamp loads
• 1.9Ω Rds(on) minimising conduction losses during switching
• 10V maximum supply voltage enabling compatibility with common vehicle domains
• Operates from -40°C to 150°C allowing wide thermal margin for engine bays

Applications

• Suitable for controlling exterior lighting circuits on vehicles
• Ideal for driving small motors in seat or mirror adjustment systems
• Used for switching heater or blower auxiliary loads in cabins
• Can be used for managing diagnostic or accessory circuits in modules
• Used with multi-channel control units requiring compact power switching

What package and mounting method does it use for PCB assembly?

It is supplied in an eight-pin SOIC package and is intended for surface-mount assembly processes.

How many control inputs does the device accept for logic interfacing?

The device provides two inputs to interface with vehicle control logic or microcontroller outputs.

What thermal performance should designers expect for harsh under bonnet locations?

The device is specified to operate up to 150°C maximum, enabling use in high-temperature automotive compartments.

Is the switch topology suited for load-side placement in vehicle circuits?

The part implements a low-side switching topology, making it appropriate for switching loads to earth in typical vehicle architectures.
