LM74502 Datasheet (Texas Instruments) - Low IQ High Side Switch Controller

LM74502, Low IQ High Side Switch Controller

The LM74502, LM74502H is a controller which operates in conjunction with an external back-to-back connected N-channel MOSFETs to realize a low loss reverse polarity protection and load disconnect solution.

The device can also be configured to drive high side MOSFET as a load switch with overvoltage
