2.3.6 TLV7031

The TLV7031 single-channel device is a low-voltage, nanoPower comparator. This device is available in an ultra-small, leadless packages as well as standard 5-pin SC70, SOT-23, VSSOP, and TSSOP packages, making the device applicable for space-critical designs like smartphones, smart meters, and other portable or battery-powered applications.

The TLV7031 offers an excellent combination of speed and power, with a propagation delay of 3 μs and a quiescent supply current of 315 nA. The benefit of fast response time at nanoPower enables power-conscious systems to monitor and respond quickly to fault conditions. With an operating voltage range of 1.6 V to 6.5 V, these comparators are compatible with 3-V and 5-V systems.

The TLV7031 device also makes sure no output phase inversion with overdriven inputs and internal hysteresis, so engineers can use this comparator for precision voltage monitoring in harsh, noisy environments where slow-moving input signals must be converted into clean digital outputs.

The TLV7031 has a push-pull output stage capable of sinking and sourcing milliamps of current when controlling an LED or driving a capacitive load. The TLV704x has an open-drain output stage that can be pulled beyond VCC, making this device appropriate for level translators and bipolar to single-ended converters.
