Automotive multichannel window supervisor with high accuracy and compact form factor

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.
