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 over-
current 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 100mΩ MOSFET switches. When this input is LOW
the AUX inputs are connected to OUT1 and OUT2 via 500mΩ 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 con-
nected together.
5V Main Supply (Input): All MAIN inputs must be connected together exter-
nally.
Channel 1 (Output): For MIC2012-1, -2 both pins must be externally con-
nected 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 over-
current condition. Toggling EN2 or removing the load will reset the circuit
breaker latch and deassert FAULT2.
