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.
