3 Description

The TPS3704-Q1 is an ASIL-A compliant low-power

precision window (UV +OV) voltage supervisor that

can be configured and is available in an 8-pin (1.6mm

x 2.9mm) SOT-23 package. This highly accurate

(±0.25%) supervisor is available as a quad, triple,

dual, and or single channel options. Each channel

can be customized to its own overvoltage and

undervoltage window detection with an upper and

lower threshold tolerance that can be symmetric or

asymmetric.

TPS3704-Q1 allows for highly accurate threshold

detection with high resolution that is designed for

systems operating on low-voltage supply rails with

narrow margin supply tolerances. In addition, the

built-in low threshold hysteresis and fixed reset delay

features prevent false reset signals when monitoring

multiple voltage rails.

The TPS3704-Q1 does not require any external

resistors for setting the overvoltage and undervoltage

reset thresholds which improves reliability for safety

systems and optimizes overall accuracy, cost, solution

size. Optional use of external resistors for design

flexibility is supported by the SENSEx pins. Separate

VDD and SENSEx pins allow monitoring of voltage

rails other than VDD or alternatively enables use of a

push-button input.
