Texas Instruments introduced Small-Size nanopower comparators TLV7031-Q1 and TLV7041-Q1

Texas Instruments TLV7031-Q1 TLV7041-Q1

Texas Instruments introduced the new low-voltage, nanopower, single-channel comparators TLV7031-Q1/ TLV7041-Q1.These comparators are available in a standard 5-pin SC70 package, making them applicable for space-critical and power conscious designs like infotainment, telematics, and head unit applications.

The TLV7031-Q1 and TLV7041-Q1 offer an excellent combination of power and speed, with a quiescent supply current of 390 nA and a propagation delay of 3 μs. 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 1.8 V, 3 V, and 5 V systems.

The TLV7031-Q1 and TLV7041-Q1 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-Q1 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-Q1 has an open-drain output stage that can be pulled beyond VCC, making it appropriate for level translators and bipolar to single-ended converters.
