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.
