Micro-package, nano-power, low-voltage comparators for space-critical designs

The TLV7031 and TLV7041 are single-channel, low-voltage, nanoPower comparators from Texas Instruments. These devices are offered in an ultra-small, leadless package measuring 0.8mm × 0.8mm as well as standard five-pin SC70 and SOT-23 packages, making them appropriate for space-critical designs like smart meters, smartphones, and other portable or battery-powered applications. The devices offer an excellent combination of speed and power, with a propagation delay of 3µs and a quiescent supply current of 335nA. The benefit of fast response time at nanoPower enables power-conscious systems to monitor and respond swiftly to fault conditions. With an operating voltage range of 1.6V to 6.5V, these comparators are compatible with 3V and 5V systems. The devices also ensure no output phase inversion with overdriven inputs and internal hysteresis, making this family of comparators ideal 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 able of sinking and sourcing milliamps of current when controlling an LED or driving a capacitive load. The TLV7041 has an open-drain output stage that can be pulled beyond VCC, making it suitable for level translators and bipolar to single-ended converters.
