Pin Description
Pin Number
Pin Name
Pin Function
1
FAULT1
Fault Status (Output): Channel 1, active-low; weak pull-up to AUX. FAULT1
is asserted LOW when channel 1 is in a thermal shutdown state or overcur-
rent condition for more than 5ms. MIC2070 latches this output in its asserted
state upon overcurrent condition. Toggling EN1 or removing the load will
reset the circuit breaker latch, and deassert FAULT1.
2
EN1
Enable (Input): Channel 1, active-high (–1) or active-low (–2). Toggling this
input also resets the latched output of the MIC2070.
3
S3#
Control (Input): When this input is high, the MAIN inputs are connected to
OUT1 and OUT2 via 100m, 500mA MOSFET switches. When this input is
LOW, the AUX inputs are connected to OUT1 and OUT2 via 500m
MOSFET switches with a current-limit threshold specified by external
resistors, RSET1 and RSET2.
4
RSET1
Current-Limt Set Resistor (Input): Channel 1. A resistor connected to this
input sets the current-limit threshold in AUX mode (S3# asserted). The
current-limit threshold is determined by approximately 18/RSET1.
5
AUX
Auxiliary 5V Supply (Input): Also used as power supply for internal circuitry.
6NC
No Connection: This pin may be connected to other pins without restriction.
7
RSET2
Current-Limit Set Resistor (Input): Channel 2. A resistor connected to this
input sets the current-limit threshold in AUX mode (S3# asserted). The
current-limit threshold is determined by approximately 18/RSET2.
8
GND
Ground
9, 10
OUT2
Channel 2 (Output): Both pins must be connected together externally.
11, 12
MAIN
5V Main Supply (Input): All MAIN inputs must be connected together
externally.
13, 14
OUT1
Channel 1 (Output): Both pins must be connected together externally.
15
EN2
Enable (Input): Channel 2, active-high (–1) or active-low (–2). Toggling this
input also resets the latched output for the MIC2070.
16
FAULT2
Fault Status (Output): Channel 2, active-low; weak pull-up to AUX. FAULT2
is asserted LOW when channel 2 is in a thermal shutdown state or overcur-
rent condition for more than 5ms. MIC2070 latches this output in it's asserted
state upon overcurrent condition. Toggling EN2 or removing load will reset
the circuit breaker latch, and deassert FAULT2.
