Description
The BTS5045-2EKA is a 45 mΩ dual channel Smart High-Side Power Switch, embedded in a PG-DSO-14-40 EP,
Exposed Pad package, providing protective functions and diagnosis. The power transistor is built by an N-channel
vertical power MOSFET with charge pump. The device is integrated in Smart6 technology. It is specially designed
to drive lamps up to 1 * P27W/P21W, as well as LEDs in the harsh automotive environment.
