ENABLE
ENABLE is a HIGH or LOW true control signal, which
activates the main MOSFET switch. ENABLE has two
voltage ranges depending on whether the switch is an
active high or active low device.. ENABLE can be wire-
OR’d with other MIC2005/2015s or similar devices
without damage to the device. ENABLE may be driven
higher than VIN, but no higher than 5.5V.
FAULT/
FAULT/ is an N-channel ‘open drain’ output, which is
asserted (LOW true) when MIC2005/2015’s either
begins current limiting or enters thermal shutdown.
In MIC2005/2015, FAULT/ asserts after a brief delay
period, usually 32 ms. This delay ensures that FAULT/
is asserted only upon valid, enduring, over-current
conditions and that transitory event error reports are
filtered out.
After a fault clears, FAULT/ remains asserted for the
delay period; 32ms for the MIC2005/2015.
Because FAULT/ is an ‘open drain’ it must be pulled
HIGH with an external resistor output and it may be
wire-OR’d with other similar outputs, sharing a single
pull-up resistor. FAULT/ may be tied to a pull-up voltage
source which is higher than VIN, but no greater than
5.5V.

Slew Rate Control (Not present with SOT23-5 (M5))
Large capacitive loads can create significant current
surges when charged through a high-side switch such
as the MIC2005/2015. For this reason, MIC2005/2015
provides built-in slew rate control to limit the initial inrush
currents upon enabling the power MOSFET switch.
Slew rate control is active upon powering up, and upon
re-enabling the load. At shutdown, the discharge slew
rate is controlled by the external load and output
capacitor.
Thermal Shutdown
Thermal
MIC2005/2015 from damage should the die temperature
exceed safe operating levels. Thermal shutdown shuts
off the output MOSFET if the die temperature reaches
145°C.
MIC2005/2015 will automatically resume operation
when the die temperature cools down to 135°C. If
resumed operation results in reheating of the die,
another
MIC2005/2015 will continue cycling between ON and
OFF states until the offending load has been removed.
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.
