FEATURES
DESCRIPTION
The TPS3779 and TPS3780 are a family of two-

Very Small Package: 1.45-mm × 1-mm µSON
channel voltage detectors with low-power and high-
Low Quiescent Current: 1.8 µA (typ)
accuracy comparators, and are available in a very
High Threshold and Hysteresis Accuracy:
small µSON package. The SENSE1 and SENSE2

operation without false triggering. This family offers
Different Hysteresis Options:
different factory-set hysteresis options of 0.5%, 1%,
0.5%, 1%, 5%, and 10%
5%, or 10%.
Temperature Range: –40°C to +125°C
The TPS3779 and TPS3780 have adjustable SENSE
Push-Pull (TPS3779) and Open-Drain
inputs that can be configured by an external resistor
divider. When the voltage at the SENSE1 or SENSE2
