Description
1, 3
1, 3
VH1, VH2
Voltage High Input 1 and Voltage High Input 2. If the voltage monitored by VH1 or VH2
drops below 0.5 V an undervoltage condition is detected. Connect to VCC when not in use.
2, 4
2, 4
VL1, VL2
Voltage Low Input 1. If the voltage monitored by VL1 or VL2 rises above 0.5 V an
overvoltage condition is detected. Tie to GND when not in use.
5, 7
5, 7
VH3, VH4
Voltage High Input 3 and Voltage High Input 4. The polarity of these inputs is determined
by the state of the SEL pin (see Table 5). When the monitored input is configured as a
positive voltage and the voltage monitored by VH3 and VH4 drops below 0.5 V, an
undervoltage condition is detected. Conversely, when the input is configured as a negative
voltage and the input drops below 0.5 V, an overvoltage condition is detected. Connect to
VCC when not in use.
6, 8
6, 8
VL3, VL4
Voltage Low Input 3 and Voltage Low Input 4. The polarity of these inputs is determined by
the state of the SEL pin (see Table 5). When the monitored input is configured as a positive
voltage and the voltage monitored by VL3 or VL4 rises above 0.5 V, an overvoltage
condition is detected. Conversely, when the input is configured as a negative voltage and
the input rises above 0.5 V, an undervoltage condition is detected. Tie to GND when not in
use.

GND
Device Ground.

10
REF
Buffered Reference Output. This pin is a 1 V reference that is used as an offset when
monitoring negative voltages. This pin can source or sink 1 mA, and drive loads up to 1 nF.
Larger capacitive loads may lead to instability. Leave unconnected when not in use.
11
11
OV
Overvoltage Reset Output. OV is asserted low if a negative polarity input voltage drops
below its associated threshold or if a positive polarity input voltage exceeds its threshold.
The ADM12914-1 allows OV to be latched low. The ADM12914-2 holds OV low for an
adjustable timeout period determined by the timer capacitor. This pin has a weak pull-up
to VCC and can be pulled up to 16 V externally. Leave this pin unconnected when not in use
12
12
UV
Undervoltage Reset Output. UV is asserted low if a negative polarity input voltage exceeds
its associated threshold or if a positive polarity input voltage drops below its threshold. UV
is held low for an adjustable timeout period set by the external capacitor tied to the TIMER
pin. The UV pin has a weak pull-up to VCC and can be pulled up to 16 V externally via an
external pull-up resistor. Leave this pin unconnected when not in use.
13
N/A1
LATCH
OV Latch Bypass Input/Clear Pin. When pulled high, the OV latch is cleared. When held
high, the OV output has the same delay and output characteristics as the UV output. When
pulled low, the OV output is latched when asserted. (Applies only to the ADM12914-1.)
N/A1
13
DIS
OV and UV Disable Input. When pulled high, the OV and UV outputs are held high
irrespective of the state of the VHx and VLx input pins. However, if a UVLO condition occurs,
the OV and UV outputs are asserted. This pin has a weak internal pull-down (2 μA) to GND.
Leave this pin unconnected when not in use. (Applies only to the ADM12914-2.)
14
14
SEL
Input Polarity Select. This three-state input pin allows the polarity of VH3, VL3, VH4, and VL4
to be configured. Connect this pin to VCC or GND, or leave it open to select one of three
possible input polarity configurations (see Table 5).
