Pin Description
Pin Number
Pin Name
Pin Function
PWRGD
Power-Good Output: Open-drain. Asserted when the voltage on the DRAIN
1
/PWRGD
pin (V
DRAIN
) is within V
PGTH
of VEE, indicating that the output voltage is
within proper specications.
MIC25XX-1
MIC2588-1 and MIC2594-1: PWRGD will be high-impedance when
1
PWRGD
V
DRAIN
is less than V
PGTH
, and will pull-down to V
DRAIN
when V
DRAIN
is
Active-High
greater than V
PGTH
. Asserted State: Open-Drain.
MIC25XX-2
MIC2588-2 and MIC2594-2: /PWRGD will pull-down to V
DRAIN
when
1
/PWRGD
V
DRAIN
is less than V
PGTH,
and will be high impedance when V
DRAIN
is
Active-Low
greater than V
PGTH
. Asserted State: Active-Low.
OV
MIC2588: Overvoltage Threshold Input. When the voltage at the OV pin is
2
Threshold
greater than the V
OVH
threshold, the GATE pin is immediately pulled low by
an internal 100礎 current pull-down.
ON
MIC2594: Turn-On Threshold. At initial system power-up or after the device
2
Turn-On Threshold
has been shut off by the OFF pin, the voltage on the ON pin must exceed
the V
ONH
threshold in order for the MIC2594 to be enabled.
UV
MIC2588: Undervoltage Threshold Input. When the voltage at the UV pin is
3
Threshold
less than the V
UVL
threshold, the GATE pin is immediately pulled low by an
internal 100礎 current pull-down. The UV pin is also used to cycle the device
off and on to reset the circuit breaker. Taken together, the OV and UV pins
form a window comparator which denes the limits of V
EE
within which the
load may safely be powered.
OFF
MIC2594: Turn-Off Threshold. When the voltage at the OFF pin is less than
3
Turn-Off Threshold
the V
OFFL
threshold, the GATE pin is immediately pulled low by an internal
100礎 current pull-down. The OFF pin is also used to cycle the device off
and on to reset the circuit breaker. Taken together, the ON and OFF pins
provide programmable hysteresis for the turn-on command voltage.
4
VEE
Negative Supply Voltage Input. Connect to the negative, or low side, terminal
of the input power supply.
5
SENSE
Circuit Breaker Sense Input: The current-limit threshold is set by connecting
a resistor between this pin and V
EE
. When the current-limit threshold of
IR = 50mV is exceeded for an internal delay t
FLT
(400祍), the circuit breaker
is tripped and the GATE pin is immediately pulled low by I
GATEOFF
. Toggling
the UV/OFF pin will reset the circuit breaker. To disable the circuit breaker,
externally connect SENSE and VEE together.
6
GATE
Gate Drive Output: Connect to the gate of an external N-Channel MOSFET.
7
DRAIN
Drain Sense Input: Connect to the drain of an external N-Channel MOSFET.
8
VDD
Positive Supply Input. Connect to the positive, or high side, terminal of the
input power supply.
