Low-Power, Dual-Voltage Detector in Small µSON Package

Check for Samples: TPS3779, TPS3780

FEATURES

DESCRIPTION

The TPS3779 and TPS3780 are a family of two-

•

Very Small Package: 1.45-mm × 1-mm µSON

Low Quiescent Current: 1.8 µA (typ)

channel voltage detectors with low-power and high-

accuracy comparators, and are available in a very

small µSON package. The SENSE1 and SENSE2

inputs include a built-in hysteresis for filtering to reject

brief glitches, thereby ensuring stable output

operation without false triggering. This family offers

different factory-set hysteresis options of 0.5%, 1%,

5%, or 10%.

High Threshold and Hysteresis Accuracy:

1.0%

•

Adjustable Thresholds

Different Hysteresis Options:

–

0.5%, 1%, 5%, and 10%

•

Temperature Range: –40°C to +125°C

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.

Push-Pull (TPS3779) and Open-Drain

(TPS3780) Output Options

APPLICATIONS

•

DSPs, Microcontrollers, or Microprocessors

Applications

The devices have a very low quiescent current of

1.8 µA (typical) and provide a precise, space-

conscious solution for voltage detection suitable for

applications. The TPS3779 and TPS3780 operate

from 1.5 V to 6.5 V, over the –40°C to +125°C

temperature range.
