BTS721L1 Description

Short technical summary and product information.

The Infineon BTS721L1 is a smart four-channel high-side power switch based on the PROFET technology. It is designed for 12V and 24V DC grounded loads, replacing electromechanical relays and discrete circuits.

 

Key electrical specifications include an overvoltage protection of 43V and an operating voltage range of 5.0V to 34V. The on-state resistance varies depending on the number of active channels, with a typical value of 25 mΩ for four parallel channels. Current limitation is typically set at 8A.

 

This device integrates several protective functions such as overload protection, current limitation, short-circuit protection, thermal shutdown, and overvoltage protection. It also features undervoltage and overvoltage shutdown with auto-restart, fast demagnetization of inductive loads, and reverse battery protection.

 

The BTS721L1 is housed in a PG-DSO20 package and is suitable for surface mounting. Its diagnostic feedback and CMOS compatible input make it compatible with microcontrollers.
