DIS (Pin 13, LTC2914-2): Output Disable Input. Disables
the OV and UV output pins. When DIS is pulled high, the
OV and UV pins are not asserted except during a UVLO
condition. Pin has a weak (2μA) internal pull-down to GND.
Leave pin open if unused.
Exposed Pad (Pin 17, DFN Package): Exposed Pad may
be left open or connected to device ground.
GND (Pin 9): Device Ground
LATCH (Pin 13, LTC2914-1):
OVLatchClear/BypassInput.
When pulled low, OV is latched when asserted. When
pulled high, OV latch is cleared. While held high, OV has
the same delay and output characteristics as UV.
OV (Pin 11): Overvoltage Logic Output. Asserts low when
any positive polarity input voltage is above threshold or
any negative polarity input voltage is below threshold.
Latched low (LTC2914-1). Held low for an adjustable
delay time after all inputs are valid (LTC2914-2). Pin has
a weak pull-up to VCC and may be pulled above VCC using
an external pull-up. Leave pin open if unused.
REF (Pin 10): Buffered Reference Output. 1V reference
used for the offset of negative-monitoring applications.
The buffered reference sources and sinks up to 1mA. The
reference drives capacitive loads up to 1nF. Larger capacitive
loads may cause instability. Leave pin open if unused.
SEL (Pin 14): Input Polarity Select Three-State Input.
Connect to VCC, GND or leave unconnected in open state
to select one of three possible input polarity combinations
(refer to Table 1).
TMR (Pin 15):
Reset Delay Timer. Attach an external
capacitor (CTMR) of at least 10pF to GND to set a reset
delay time of 9ms/nF. A 1nF capacitor will generate an
8.5ms reset delay time. Tie pin to VCC to bypass timer.
UV(Pin12):UndervoltageLogicOutput.Assertslowwhen
any positive polarity input voltage is below threshold or
any negative polarity input voltage is above threshold.
Held low for an adjustable delay time after all voltage
inputs are valid. Pin has a weak pull-up to VCC and may
be pulled above VCC using an external pull-up. Leave pin
open if unused.
VCC (Pin 16): Supply Voltage. Bypass this pin to GND with
a 0.1μF (or greater) capacitor. Operates as a direct supply
input for voltages up to 6V. Operates as a shunt regulator for
supply voltages greater than 6V and must have a resistance
between the pin and the supply to limit input current to no
greater than 10mA. When used without a current-limiting
resistance, pin voltage must not exceed 6V.
VH1/VH2 (Pin 1/Pin 3): Voltage High Inputs 1 and 2. When
the voltage on this pin is below 0.5V, an undervoltage
condition is triggered. Tie pin to VCC if unused.
VH3/VH4 (Pin 5/Pin 7): Voltage High Inputs 3 and 4. The
polarity of the input is selected by the state of the SEL pin
(refer to Table 1). When the monitored input is congured
as a positive voltage, an undervoltage condition is trig-
gered when the pin is below 0.5V. When the monitored
input is congured as a negative voltage, an overvoltage
condition is triggered when the pin is below 0.5V. Tie pin
to VCC if unused.
VL1/VL2 (Pin 2/Pin 4): Voltage Low Inputs 1 and 2. When
the voltage on this pin is above 0.5V, an overvoltage condi-
tion is triggered. Tie pin to GND if unused.
VL3/VL4 (Pin 6/Pin 8): Voltage Low Inputs 3 and 4. The
polarity of the input is selected by the state of the SEL pin
(refer to Table 1). When the monitored input is congured
as a positive voltage, an overvoltage condition is triggered
when the pin is above 0.5V. When the monitored input is
congured as a negative voltage, an undervoltage condi-
tion is triggered when the pin is above 0.5V. Tie pin to
GND if unused.
