Pin Function
Fault Status (Output): Internal pull-up or open-drain. Asserted LOW when
Channel is in a thermal shutdown state or overcurrent condition for more
than 5ms. MIC2072 latches this output in its asserted state upon an
overcurrent condition. Toggling EN1 or removing the load will reset the
circuit breaker latch and deassert FAULT1.
Enable (Input): Channel 1, active-high (–1) or active-low (–2). Toggling this
input also resets the latched output of the MIC2072.
Control (Input): When this input is HIGH, the MAIN inputs are connected to
OUT1 and OUT2 via 100m
AUX inputs are connected to OUT1 and OUT2 via 500m MOSFET
switches.
Auxiliary 5V Supply (Input): Also used as power supply for internal circuitry.
No Connection: This pin may be connected to other pins without restriction.
Ground
Channel 2 (Output): For MIC2012-1, -2 both pins must be externally
connected together.
5V Main Supply (Input): All MAIN inputs must be connected together
externally.
Channel 1 (Output): For MIC2012-1, -2 both pins must be externally
connected together.
Enable (Input): Channel 2, active-high (–1) or active-low (–2). Toggling this
input also resets the latched output of the MIC2072.
Fault Status (Output): Internal pull-up or open-drain. Asserted LOW when
Channel 2 is in a thermal shutdown state or overcurrent condition for more
than 5ms. MIC2072 latches this output in its asserted state upon an
overcurrent condition. Toggling EN2 or removing the load will reset the
circuit breaker latch and deassert FAULT2.
