SGM25733Q
Automotive GradeLow Quiescent Current Ideal Diode Controller with Reverse Battery Protection
The SGM25733Q, an ideal diode controller used as an ideal diode rectifier with external NMOS, offers low-loss reverse polarity protection, which has a mere 20mV forward voltage drop. 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 downs 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.
Controlling the GATE of MOSFET, the device regulates the 20mV forward voltage drop. The control architecture ensures the external MOSFET turns off in the event of reverse current, effectively preventing any steady-state reverse current flow. With a rapid reverse current blocking response time of less than 0.88μs, the device is well-suited for applications requiring output voltage hold-up during ISO7637 pulse tests, as well as during input micro-short and power fail scenarios.
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 1.2μA 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 SGM25733Q is available in a Green SOT-23-6 package.
