Infineon BTS6143DAUMA1 High Side 1, High Side Power Switch Power Switch IC 5-Pin, TO-252

This power-switch IC is a dual high-side switch designed for automotive applications, providing controlled power delivery to two loads from a single input. It is intended for surface-mount installation in a TO-252 package and operates across a broad supply range, supporting conventional vehicle electrical systems. The device offers robust thermal tolerance for demanding environments and integrates protective and control functions suitable for vehicle electronic loads.

• Low on-resistance of 24 mΩ reduces conduction losses
• High continuous current rating of 41A supports heavy loads
• Wide supply window from 5.5V to 38V accommodates vehicle systems
• Dual outputs with single input simplify wiring and control
• Peak operating temperature tolerance to 150 °C enables hot environments

• Suitable for switching automotive actuators and motors
• Ideal for powering heating and ventilating blower units
• Used with relay-replacement load-management systems
• Can be used for lighting circuits requiring high current
• Suitable for integration into body control modules

It is supplied in a TO-252 package designed for surface-mount assembly on standard boards.

The component has a 5-pin footprint to accommodate input, outputs and control connections.

The device is rated to operate from -40 °C up to a maximum of 150 °C, covering cold starts and high-temperature engine-bay conditions.

It offers two separate outputs, allowing distribution of power to two distinct loads from one input.
