BTS728L2 Description

Short technical summary and product information.

The Infineon Technologies BTS728L2 is a smart high-side power switch designed for 5V, 12V, and 24V grounded loads. It features two channels with a low on-state resistance of 50mΩ typical.

 

This device offers robust protection functions including short circuit protection, overload protection, current limitation, thermal shutdown, and overvoltage protection. It also provides diagnostic feedback with an open-drain output, enabling open load detection in the ON-state and feedback of thermal shutdown.

 

The BTS728L2 is suitable for various applications, including driving resistive, inductive, and capacitive loads, especially those with high inrush currents like lamps. It replaces electromechanical relays and discrete circuits, offering improved electromagnetic compatibility and low standby current.

 

Packaged in a 20-SOIC (0.295", 7.50mm Width) surface-mount case, this component is designed for general-purpose switching applications.
