ProFET® BTS720L1 is a Smart Four Channel Highside Power Switch featuring overload protection, current limitation, short-circuit protection, thermal shutdown, overvoltage protection (including load dump), reverse battery protection, undervoltage and overvoltage shutdown with auto-restart and hysteresis, open drain diagnostic output, open load detection in ON-state, CMOS compatible input, loss of ground and loss of Vbb protection, electrostatic discharge (ESD) protection. It is suitable for 12 V DC grounded loads with diagnostic feedback for µC compatible power switch, and most suitable for resistive and lamp loads, which can replace electromechanical relays and discrete circuits.
The Siemens BTS720L1 is a smart four‑channel high‑side power switch built with N‑channel vertical power FETs and integrated charge‑pump technology. It offers over‑voltage, overload, short‑circuit, thermal shutdown, reverse‑battery and ESD protection, making it suitable for replacing electromechanical relays in 12 V DC grounded loads.
The document provides detailed electrical characteristics, maximum ratings, pin definitions, truth tables, and package dimensions. It also describes input and status feedback, protection functions, and wiring guidelines for parallel channel operation.
