TLV7031/TLV7041 Nanopower Comparators

Texas Instruments' TLV7031 and TLV7041 are single-channel, low-voltage, nanopower comparators. These devices are available in an ultra-small, leadless package measuring 0.8 mm x 0.8 mm as well as standard 5-pin SC70 and SOT-23 packages. Their small size makes them applicable for space-critical designs like smartphones, smart meters, and other portable or battery-powered applications.

The TLV7031 and TLV7041 offer an excellent combination of speed and power, with a propagation delay of 3 µs and a quiescent supply current of 335 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 and TLV7041 also ensure no output phase inversion with overdriven inputs and internal hysteresis, so engineers can use this family of comparators 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 TLV7041 has an open-drain output stage that can be pulled beyond V_CC, making it appropriate for level translators and bipolar to single-ended converters.
