BTS70402EPAXUMA1 Description

Short technical summary and product information.

The BTS70402EPAXUMA1 from Infineon Technologies is a smart high-side power switch belonging to the PROFET™ +2 12V family. It integrates protection and diagnosis functions, making it suitable for driving resistive, inductive, and capacitive loads.

 

This device offers two N-channel outputs with a nominal load current capability of 3.5A at 85°C. Key electrical specifications include a minimum operating voltage of 4.1V and a maximum of 28V, with overvoltage protection clamping at 35V. The ON-state resistance is typically 19mΩ, and a typical current sense ratio of 1800 is provided.

 

Protection features include current limiting, open load detection, over-temperature, overvoltage, and undervoltage lockout (UVLO). It operates within a temperature range of -40°C to 150°C (TJ). The switch type is general purpose with an On/Off interface.

 

The BTS70402EPAXUMA1 is supplied in a PG-TSDSO-14-22 package, a 14-TSSOP with an exposed pad, designed for surface mounting. It is qualified for automotive applications according to AEC-Q100 Grade 1.
