Infineon HITFET Series Power Switch IC, 60V Maximum Supply Voltage, 6A Operating Current - BTS3018TCATMA1


This power switch IC is a low-side semiconductor designed for automotive applications meeting AEC expectations and intended for surface-mount deployment. It controls power flow in vehicle circuits across a broad supply range and supports dual-output switching with a single input, operating in demanding thermal conditions while handling moderate currents.

Features and Benefits:


• Low-side configuration enables controlled grounding of loads
• Handles up to 6 A operating current for moderate load demands
• Operates from 2 V to 60 V to accommodate varied vehicle rails
• Low RDS(on) of 44 mΩ reduces conduction losses
• Rated for −40 °C to 150 °C to tolerate extreme temperatures
• Surface-mount TO-263 package simplifies automated assembly

Applications


• Suitable for switching automotive lighting and signalling loads
• Ideal for controlling small motors and actuators in vehicles
• Used with multiplexed body control modules for dual outputs
• Can be used for protection and load-disconnect functions
• Suitable for junction-box and power-distribution modules

How many external control lines are required to operate it?


It uses one input to govern two separate outputs.

What pin count should designers allocate on the PCB footprint?


The component requires a 3-pin footprint for electrical connections.

What mounting style is needed during assembly?


It requires surface-mounted placement compatible with TO-263 soldering.

What physical envelope should be allowed for thermal management?


Allow for a component measuring 15 mm by 10 mm with 4.4 mm height in the layout.

What topology does it implement for load switching?


It implements a low-side switching topology for grounding loads.
