• Embedded protection functions (e.g. over current shutdown, over temperature shutdown)
• Infineon® INTELLIGENT LATCH
• Green Product (RoHS compliant)
• AEC Qualified
Description
Embedded in a PG-TO252-5-311 package, the BTS50060-1TEA is a 6msingle channel Smart High-Side Power
Switch. It is based on Smart power chip on chip technology with a P-channel vertical power MOSFET, providing
protective and diagnostic functions. It is specially designed to drive loads in the harsh automotive environment.
