Pin Function
Enable (Input): Logic-compatible enable input (-1 version is active high, -2
version is active low). High input >1.8V typical; low input <1.4V typical.
Do not float.
MIC2549A only: Also resets thermal shutdown latch.
Fault Flag (Output): Active-low, open-drain output. Indicates overcurrent or
thermal shutdown.
MIC2549A only: Latched low on thermal shutdown.
Ground: Supply return.
Current Limit: Sets current limit threshold using an external resistor (R
connected to ground. 76.8 < R
Supply Input: Output MOSFET drain. Also powers internal circuitry. Both IN
pins must be externally connected together.
Switch Output: Output MOSFET source. Both OUT pins must be externally
connected together.
Not internally connected
