Description

The TLV185x -Q1 and TLV186x -Q1 are a family of Automotive grade nanopower, 40 Volt comparators with single, dual and quad channel options. The family offers fail-safe (FS) inputs with push-pull and open-drain output options. These features coupled with nanopower operation over the wide supply range of 1.8 V to 40 V make this family well-suited for house-keeping functions such as voltage and temperature monitoring in low-power, always-on systems. All devices include a Power-On Reset (POR) feature that ensures 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 inputs have over-the-rail capability where both inputs can exceed the supply voltage up to 40 V and still operate properly. This makes the comparators well suited for both high and low supply voltage systems without limiting the range of input voltages that can be compared. Likewise, the internal reverse battery protection feature prevents damage to the comparator in the event of improper battery installation to the supply pins. The TLV185x -Q1 comparators have a push-pull output stage where as the TLV186x -Q1 comparators have an open-drain output stage, making it appropriate for level translation.
