Compact new low-power high-accuracy two-channel voltage detectors

This post is sponsored by Texas Instruments. The TPS3779 and TPS3780 are members of a new family of compact low-voltage high-accuracy two-channel voltage detectors from Texas Instruments (TI). The devices' SENSE1 and SENSE2 inputs include hysteresis to reject brief glitches, ensuring stable output operation without false triggering. The family offers different factory-set hysteresis options of 0.5%, 1%, 5%, or 10%. The TPS3779 and TPS3780 have adjustable SENSE inputs that can be configured by an external resistor divider. When the voltage at the SENSE1 or SENSE2 input goes below the falling threshold, OUT1 or OUT2 is driven low, respectively. When SENSE1 or SENSE2 rises above the rising threshold, OUT1 or OUT2 goes high, respectively. The devices have a very low quiescent current of 2 µA (typical) and provide a precise, space-conscious solution for voltage detection suitable for low-power system-monitoring and portable applications. The TPS3779 and TPS3780 operate from 1.5V to 6.5V, over the -40C to 125C temperature range.
