Pin Function Description (For AS2316)
Pin Number
Function
Description
1
V
CC
Power input to the chip.
2
+12 V
Input for overvoltage and undervoltage for the +12 V rail.
3
+5 V
Input for overvoltage and undervoltage for the +5 V rail.
4
+3.3
Input for overvoltage and undervoltage for the +3.3V rail.
5
–5 V
Input for overvoltage and undervoltage for the –5 V rail.
6
–12 V
Input for overvoltage and undervoltage for the –12 V rail. This function may
disabled by tying this pin to a positive voltage above 2.4 V.
7
GND
Signal ground and silicon substrate.
8
HYST
Open collector output of the AC undervoltage comparator. A resistor between this pin
and AC will provide hysteresis to the AC undervoltage sensing.
9
OFF
Pulling this pin low will reset the FAULT latch and discharge the start-up timing
capacitors, UVB and PG CAP, allowing normal start-up for the system. Pulling this pin
high will send the FAULT signal high, prompting a system shutdown.
10
AC
Non-inverting input to the AC undervoltage sensing comparator. If the AC pin is
less than 2.5 V, POK goes low and UVB cap discharges.
11
PG CAP
A cap to ground provides a delay between undervoltage sensing becoming good
and the POK output going high. Cap discharges whenever an output or AC
undervoltage is detected.
12
POK
Open collector output of the undervoltage sensing comparators. This pin goes low
upon an undervoltage condition. Except for the delay set by the PG CAP, this pin
always reflects the actual state of the undervoltage sensing.
13
DELAY
A cap to ground will delay the FAULT signal when the OFF pin is used to shut down
the system. The POK will signal a power fail warning immediately, but the FAULT
shutdown of the power supply will be delayed.
14
UVB
A cap to ground provides start-up blanking of the undervoltage sensing portion of the
FAULT signal. This pin may also be grounded to prevent undervoltage conditions from
triggering the FAULT signal. This pin discharges the cap whenever AC goes low or
FAULT pin goes high.
15
V
REF
2.5 V Voltage reference. This is a series regulator type reference.
16
FAULT
Open collector output of the overvoltage and undervoltage comparators.
