Pin Description
Pin Number
Pin Name
Pin Function
1
ON
Enable Input: When the voltage at the ON pin is higher than the V
ONH
threshold, a start cycle is
initiated. An internal current source (I
GATEON
) is activated which charges the GATE pin, ramping
up the voltage at this pin to turn on an external MOSFET. Whenever the voltage at the ON pin is
lower than the V
ONL
threshold, an undervoltage lockout condition is detected and the I
GATEON
current source is disabled while the GATE pin is pulled low by I
GATEOFF
. After a load current fault,
toggling the ON pin LOW then back HIGH will reset the circuit breaker and initiate another start
cycle.
2
FB
Output Voltage Feedback Input: This pin is connected to an external resistor divider that is used
to sample the output load voltage. The voltage at this pin is measured against an internal
comparator whose output controls the PWRGD (or /PWRGD) signal. PWRGD (or /PWRGD)
asserts when the FB pin voltage crosses the V
FBH
threshold. When the FB pin voltage is lower
than its V
FBL
threshold, PWRGD (or /PWRGD) is de-asserted. The FB comparator exhibits a
typical hysteresis of 80mV.
The FB pin voltage also affects the MIC2587/MIC2587Rs foldback current limit operation (see
the Functional Description section for further information).
