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.
