For battery-operated electronic systems in automotive applications, battery supply remains on even when ignition is off, to support features like remote key entry and security which are required even in ignition-off state. To maximize battery life, there is a need for power protection solutions to provide robust reverse protection while maintaining low supply current.
In an automotive system, the low IQ during sleep mode/ignition off state is generally achieved by following approaches:
LM7472x-Q1 devices enable <35uA quiescent current without dependency on MCU EN control signal or an external signal through a wire, making the device more suitable in comparison.
