connected to ground. 154Ω < R
Switch (Output): Output MOSFET source. Pins 6 and 8 must be externally
connected.
Pin Function
Enable (Input): Logic-compatible enable input. Active-high (-1) or active-
low (-2). High input >1.7V typical; low input <1.5V typical. Do not float.
MIC2548 only: Also resets thermal shutdown latch.
Fault Flag (Output): Active-low, open-drain output. Indicates overcurrent
or thermal shutdown conditions. MIC2548 only: latched low on thermal
shutdown.
Ground.
Current Limit: Sets current-limit threshold using an external resistor, R
Input: Output MOSFET drain. Also powers internal circuitry.
Not internally connected.
