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.
