Infineon BTS452T Series Power Switch IC, 41.6W Power Rating, 52V Maximum Supply Voltage - BTS452TATMA1

This power switch IC is a high-side automotive load controller designed for vehicle electrical systems, providing controlled switching of multiple outputs while operating across a wide supply range. It is suited to handle moderate currents for several channels simultaneously and is delivered in a surface-mount TO-252 package for integration into compact assemblies.

Features and Benefits:

• 5 outputs providing independent load control and simplified wiring
• 2.2A operating current enabling sustained moderate load operation
• 52V maximum supply voltage supporting high-voltage automotive systems
• 6V minimum supply voltage ensuring operation during low-voltage conditions
• 380mΩ Rds(on) minimising conduction losses for improved efficiency
• 41.6W power rating allowing reliable dissipation under load

Applications

• Used for switching multiple lighting circuits in vehicles
• Ideal for controlling electric motors of auxiliary systems
• Suitable for body control modules managing distributed loads
• Can be used for power distribution in hybrid vehicle subsystems
• Used with harnessed sensor clusters requiring individual channel switching

What thermal range can be expected during typical operation?

The device is specified to operate between -40°C and 150°C, accommodating engine-bay temperature variations and elevated under-bonnet conditions.

How many pins and what mounting style are required on the board?

The component uses a 5-pin footprint and is intended for surface-mount placement in TO-252 format for compact assembly.

How does the topology affect protection strategies in a system?

As a high-side topology, it places switching on the supply side of loads, simplifying low-side sensing and enabling centralised reverse-protection and short-circuit management at the source.
