The Infineon Technologies BTS70401EPZXUMA1 is a smart high-side power switch designed for automotive applications. It offers integrated protection against overcurrent, overtemperature, undervoltage, and short circuits, along with diagnostic capabilities like proportional load current sensing and open load detection.
This device is part of the PROFET™ +2 12V family and features a low ON-state resistance of 19 mΩ typical. It supports a wide operating voltage range from 3.1V to 28V and can handle nominal load currents up to 4.5A at 85°C. The operating temperature range extends up to 175°C junction temperature, making it suitable for under-the-hood applications.
Packaged in a PG-TSDSO-14, the BTS70401EPZXUMA1 is surface-mount compatible. Its features include ReverseON for low power dissipation in reverse polarity conditions and InverseON for switch-on capability during inverse current. It is qualified for automotive applications according to AEC-Q100 Grade 0.
Potential applications include driving resistive, inductive, and capacitive loads, replacing electromechanical relays and fuses, and handling high inrush current loads such as P27W + R5W lamps or equivalent LED modules. It is also suitable for powertrain systems like transmission applications.
