BTS71220-4ESA Description

Short technical summary and product information.

The Infineon BTS71220-4ESA is a Serial Interface Power Controller (SPOC™ +2) that integrates high-side switching with advanced protection and diagnostic capabilities. It is suitable for driving resistive, inductive, and capacitive loads, and can replace electromechanical relays and fuses.

Key electrical specifications include a minimum operating voltage of 4.1V (at switch ON) and a maximum operating voltage of 28V. The digital supply voltage is compatible with 3.3V and 5V logic. The device features a maximum ON-state resistance of 16.5 mΩ for channels 0 and 3, and 22.5 mΩ for channels 1 and 2 at 150°C.

Protection features include absolute and dynamic temperature limitation, overcurrent protection with programmable restart control, undervoltage shutdown, and overvoltage protection with external components. Diagnostic features include proportional load current sense, open load detection in ON and OFF states, and short circuit detection to ground and battery, with feedback via SPI.

This device is qualified for automotive applications according to AEC-Q100 Grade 1. It comes in a PG-TSDSO-24 package.
