3 Description
The TPS3779 and TPS3780 are a family of high-
accuracy, two-channel voltage detectors with low- power and small solution size. The SENSE1 and
SENSE2 inputs include hysteresis to reject brief
glitches, ensuring stable output operation without
false triggering. This 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 1.5 V to 6.5 V,
over the –40°C to 125°C temperature range.
