ENABLE
Only parts in bold have ENABLE pin.
ENABLE pin is a logic compatible input which activates
the main MOSFET switch thereby providing power to the

LOW control signal. The MIC20XX can operate with
logic running from supply voltages as low as 1.5 V.
ENABLE may be driven higher than V
than 5.5V and not less than –0.3V.
FAULT/
Only parts in bold have FAULT/ pin.
FAULT/ is an N-channel open-drain output, which is
asserted (LOW true) when switch either begins current
limiting or enters thermal shutdown.
FAULT/ asserts after a brief delay when events occur
that may be considered possible faults. This delay
insures that FAULT/ is asserted only upon valid,
enduring, over-current conditions and that transitory
event error reports are filtered out.
In MIC200X FAULT/ asserts after a brief delay period, of
32ms typical. After a fault clears, FAULT/ remains
asserted for the delay period of 32ms
MIC201X’s FAULT/ asserts at the end of the Kickstart™
period which is 128ms typical. This masks initial current
surges, such as would be seen by a motor load starting
up. If the load current remains above the current limit
threshold after the Kickstart™ has timed out, then the
FAULT/ will be asserted. After a fault clears, FAULT/
remains asserted for the delay of 128ms.
Because FAULT/ is an open-drain it must be pulled
HIGH with an external resistor and it may be wire-OR’d

Soft-start Control
Large capacitive loads can create significant inrush
current surges when charged through the switch. For
this reason, the MIC20XX family of switches provides a
built-in soft-start control to limit the initial inrush currents.
Soft-start is accomplished by controlling the power
MOSFET when the ENABLE pin enables the switch.

output voltage ramp at turn-on. This input allows
designers the option of decreasing the output’s slew rate
(slowing the voltage rise) by adding an external
capacitance between the C
Thermal Shutdown
Thermal shutdown is employed to protect the MIC20XX
family of switches from damage should the die
temperature exceed safe operating levels. Thermal
shutdown shuts off the output MOSFET and asserts the
FAULT/ output if the die temperature reaches 145°C.
The switch will automatically resume operation when the
die temperature cools down to 135°C. If resumed
operation results in reheating of the die, another
shutdown cycle will occur and the switch will continue
cycling between ON and OFF states until the overcurrent
condition has been resolved.
Depending on PCB layout, package type, ambient
temperature, etc., hundreds of milliseconds may elapse
from the incidence of a fault to the output MOSFET
being shut off. This delay is due to thermal time
constants within the system itself. In no event will the
device be damaged due to thermal overload because die
temperature is monitored continuously by on-chip
circuitry.
