Infineon HITFET Series Power Switch IC, 3.8W Power Rating, 42V Maximum Supply Voltage - BTS3110NHUMA1

This power switch IC is a low-side automotive load switch designed to control multiple vehicle circuits from a single input. It operates across a wide temperature range and is intended for surface-mounted applications, providing compact power control suitable for automotive electrical systems.

Features and Benefits:

• Low on-resistance of 220mΩ reduces conduction losses
• Rated for up to 42V supply to handle vehicle electrical transients
• Operates from -40°C to 150°C for harsh environments
• Supports 1.4A operating current for moderate loads
• Four-pin SOT-223 package enables straightforward surface mounting

Applications

• Suitable for switching vehicle auxiliary loads and sensors
• Ideal for distribution to multiple low-side loads in cabins
• Used with 12V/24V systems requiring 42V transient margin
• Can be used for driving resistive and small inductive loads
• Suitable for compact ECU or module power management

How many outputs can be driven from a single input with this device?

The device is configured to control five outputs from one input, allowing centralised switching of multiple circuits.

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

It is supplied in a four-pin SOT-223 package intended for surface-mount placement on a PCB.

What continuous power dissipation should designers expect?

The device has a power rating of 3.8W, which defines its steady-state dissipation capability under specified conditions.

What pin count should be accommodated in board layouts?

Designers should allow for four pins when creating the PCB footprint for this component.
