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 makes sure 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 powerdown.

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.
