Function
Enable input. This pin is the MOSFET switch driver logic input. Both active-HIGH
(-1 suffix) and active-LOW (-2 suffix) logic devices are available.
Fault flag output. This open-drain output goes into an active-LOW state in response to
undervoltage, current limit or thermal shutdown conditions.
Ground. Power supply return for the internal circuitry of the IC.
No connection. These pins have no internal connections to the device.
No connection. This pin has no internal connection to the device. Connect pins 6 and 8 to
maintain pin-compatibility with the MIC2525.
Positive power supply voltage input. This is the switching MOSFET drain connection
as well as the positive supply for the IC.
MOSFET source. The output pin supplies power to the load.
