OV (Pin 6/Pin 3, LTC2912-3): Overvoltage Logic Output.
Asserts high with a weak internal pull-up to VCC when the
VL input is above threshold. Latches high. May be pulled
above VCC using an external pull-up. Leave pin open if
unused.
TMR (Pin 4/Pin 5): 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 (Pin 7/Pin 2): Undervoltage Logic Output. Asserts low
when the VH input voltage is below threshold. Held low for
a programmed delay time after the VH input is 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 1/Pin 8): 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
should 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.
VH (Pin 2/Pin 7): Voltage High Input. When the voltage
on this pin is below 0.5V, an undervoltage condition is
triggered. Tie pin to VCC if unused.
VL (Pin 3/Pin 6): Voltage Low Input. When the voltage on
this pin is above 0.5V, an overvoltage condition is triggered.
Tie pin to GND if unused.
