The TPS3703-Q1 device is an integrated overvoltage (OV) and undervoltage (UV) monitor or
reset IC in industry’s smallest 6-pin DSE package. This highly accurate voltage supervisor is ideal
for systems that operate on low-voltage supply rails and have narrow margin supply tolerances. Low
threshold hysteresis prevent false reset signals when the monitored voltage supply is in its normal
range of operation. Internal glitch immunity and noise filters further eliminate false resets
resulting from erroneous signals.
The TPS3703-Q1 does not require any external resistors for setting overvoltage and
undervoltage reset thresholds, which further optimizes overall accuracy, cost, solution size, and
improves reliability for safety systems. The Capacitor Time (CT) pin is used to select between the
two available reset time delays designed into each device and also to adjust the reset time delay
by connecting a capacitor. A separate SENSE input pin and VDD pin allow for the redundancy sought
by high-reliability systems.
This device has a low typical quiescent current specification of 4.5 µA (typical).
The TPS3703-Q1 is suitable for automotive applications and is qualified for AEC-Q100 Grade
