NAME
FUNCTION

SET1
Set Monitored Threshold 1 Input. Monitor a voltage by setting the threshold with an
external resistive divider. The SET1 threshold is 0.5V.
Open-Drain Overvoltage Output. When any of the SET_ voltages exceed their 0.55V
19
19
OV_OUT
overvoltage threshold, OV_OUT goes low. When all of the SET_ voltages are below their
overvoltage threshold, OV_OUT goes high impedance after a short propagation delay.
Open-Drain Reset Output. When any of the monitored voltages (including EN) falls below
its threshold, SHDN is pulled low, or FAULT is pulled low, RESET asserts and stays
20
20
RESET
asserted for at least the minimum reset timeout period after all of these conditions are
removed. The reset timeout is 128ms (typ) when TIMEOUT is connected to ABP or can be
adjusted by connecting a capacitor from TIMEOUT to GND.
FAULT Synchronization Input/Output. While EN = SHDN = high, FAULT is pulled low when
21
21
FAULT
any of the SET_ voltages falls below their respective threshold. Pull FAULT low manually to
assert a simultaneous power-down. FAULT is internally pulled up to ABP by a 100k ?
resistor.
22
22
SHDN
Active-Low Shutdown Input. When SHDN is pulled low, the device will reverse sequence
for power-down operation. SHDN is internally pulled up to ABP by a 100k ? resistor.
Adjustable Sequence Delay Timing Input. Connect a capacitor from DELAY to GND to set
23
23
DELAY
the sequence delay between each OUT_. Leave DELAY unconnected for a 10μs (typ)
delay.
Adjustable Reset Timeout Input. Connect a capacitor from TIMEOUT to GND to set the
24
24
TIMEOUT
reset timeout period. Connect TIMEOUT to ABP for the fixed timeout of 128ms (typ). Leave
TIMEOUT unconnected for a 10μs (typ) delay.

SEQ2
SEQ3
Sequence Order Select Inputs. SEQ1, SEQ2, and SEQ3 allow the order of sequencing for
each supply to be programmable (Table 1).
Charge-Pump Output. An internal charge pump boosts CP_OUT to (V CC + 5V ) to provide
28
28
CP_OUT
a pullup voltage that can be used to drive external n-channel MOSFETs. CP_OUT sources
up to 25μA.

DISC5
OUT5
SET5
EP
Discharge Pulldown Input 5. During normal operation, DISC5 is high impedance. During a
fault condition or power-down, DISC5 provides an 85mA sink current.
Open-Drain Output 5. When the voltage at SET4 is above 0.5V, OUT5 goes high
impedance. OUT5 requires an external pullup resistor and can be pulled up to 13.2V.
External Set Monitored Threshold 5. Monitor a voltage by setting the threshold with an
external resistive divider. The SET5 threshold is 0.5V.
Exposed Pad. EP is internally connected to GND. Connect EP to the GND plane for
improved heat dissipation. Do not use EP as the only ground connection.
