BTS500551TMCATMA1 Description

Short technical summary and product information.

The Infineon Technologies BTS500551TMCATMA1 is a smart high-side N-channel power switch suitable for 12V DC grounded loads. It operates within a voltage range of 5.0 to 34V and features a low on-state resistance of 6.0 mOhm typical.

 

This device provides robust protection, including overload, current limitation, short circuit, over-temperature, and over-voltage protection. It also offers diagnostic feedback with load current sense and open load detection. The switch is designed for applications requiring high inrush current, such as lamps and motors, and can replace electromechanical relays and fuses.

 

Packaged in a TO-263-8, D²Pak (7 Leads + Tab), TO-263CA, the BTS500551TMCATMA1 is surface-mount compatible. It operates across a wide temperature range of -40°C to 150°C (TJ).

 

Key electrical characteristics include a nominal current of 17A, an ISO load current of 70A, and a short circuit current limitation of 130A. The current sense ratio is 14000:1, and the interface is On/Off.
