TLV7031DPWR

The TLV7031/TLV7041 (single-channel), TLV7032/42 (dual-channel), and TLV7034/44 (quad-channel) are low-voltage, nano-power comparators. These devices are available in ultra-small leadless packages as well as standard 5-pin SC70, SOT-23, VSSOP, and TSSOP packages, making them suitable for space-constrained designs such as smartphones, smart meters, and other portable or battery-powered applications. The TLV703x and TLV704x offer an excellent combination of speed and power consumption, with a propagation delay of 3µs and a quiescent supply current of 315nA. Thanks to their fast response at nano-power levels, power-sensitive systems can monitor fault conditions and respond quickly. These comparators operate over a voltage range of 1.6V to 6.5V, making them compatible with 3V and 5V systems. The TLV703x and TLV704x also feature overdrive inputs and internal hysteresis to ensure no output phase reversal, allowing engineers to use this family of comparators for precise voltage monitoring in harsh, noisy environments where slow input signals must be converted to clean digital outputs. The TLV703x has a push-pull output stage capable of sinking/sourcing milliamps of current, enabling LED control or driving capacitive loads. The TLV704x has an open-drain output stage that can be pulled up above VCC, making it suitable for level shifters and bipolar-to-single-ended converters.
