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 open-drain 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 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.
