3 Description

The TLV1812-EP and TLV1822-EP are 40V dual

channel comparators with multiple output options.

The family offers rail to-rail inputs with push-pull

or open-drain output options. These devices also

haves an excellent speed-to-power combination with

a propagation delay of 420ns with a full supply voltage

range of 2.4V to 40V and a quiescent supply current

of only 5μA 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 TLV1812-EP device has 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 TLV1822-EP device

has an open-drain output stage that can be pulled up

to 40V independent of comparator supply voltage.

These comparators are available in the SOT23-8

packages and are specified for the extended

temperature range of –55°C to +125°C.
