  • Low supply current: 440nA per channel
  • Wide supply range: 1.8V to 40V
  • Over-the-rail inputs: common-mode range extends 40V above (V-) independent of (V+)
  • Fail-safe: high impedance inputs with no supply
  • Power-on-reset provides a known startup condition
  • No phase reversal for overdriven inputs
  • Reverse battery protection up to 40V
  • Push-pull output option (TLV185x)
  • Open-drain output option (TLV186x)
  • Temperature range: -40°C to +125°C

The TLV185x and TLV186x are a family of nanopower, 40V 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 1.8V to 40V 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 makes sure that 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 40V 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 comparators have a push-pull output stage where as the TLV186x comparators have an open-drain output stage, making it appropriate for level translation.
