3 Description
The TLV181x-Q1 and TLV182x-Q1 are a family of
Automotive grade 40 Volt single, dual and quad
channel comparators with multiple output options. The
family offers rail-to-rail inputs with push-pull or opendrain
output options. The family has an excellent
speed-to-power combination with a propagation delay
of 420 ns with a full supply voltage range of 2.4 V to
40 V with a quiescent supply current of only 5 μA per
channel.
All devices include a Power-On Reset (POR) feature.
This ensures the output is in a known state until the
minimum supply voltage has been reached before the
output responds to the inputs, thus preventing false
outputs during system power-up and power-down.
The TLV181x-Q1 comparators have a push-pull
output stage capable of sinking and sourcing
milliamps of current when controlling an LED or
driving a capacitive load such as a MOSFET gate.
The TLV182x-Q1 comparators have an open-drain
output stage that can be pulled up to 40 V
independent of comparator supply voltage.
