The SGM257301Q is a reverse polarity protection controller with an external NMOS and offers low-loss reverse polarity protection. Its 3.2V to 65V wide supply input range facilitates control over various DC bus voltages commonly found in automotive battery systems like 12V, 24V, and 48V. The device supports input voltage down to 3.2V, making it well-suited for automotive systems with stringent cold crank conditions. It also protects connected loads against reverse supply voltages as low as -65V.
This controller incorporates a charge pump gate driver for an external NMOS. Its high voltage rating simplifies system designs for automotive EMC transient interference standard ISO7637. When the enable pin is held low, the controller remains disabled and consumes only about 1.1μA of supply current.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM257301Q is available in a Green TSOT-23-8 package.
