Description for the TPS3703

The TPS3703 device is an integrated overvoltage (OV) and undervoltage (UV) monitor orreset IC in industry’s smallest 6-pin DSE package. This highly accurate voltage supervisor is idealfor systems that operate on low-voltage supply rails and have narrow margin supply tolerances. Lowthreshold hysteresis prevent false reset signals when the monitored voltage supply is in its normalrange of operation. Internal glitch immunity and noise filters further eliminate false resetsresulting from erroneous signals.

The TPS3703 does not require any external resistors for setting overvoltage andundervoltage reset thresholds, which further optimizes overall accuracy, cost, solution size, andimproves reliability for safety systems. The Capacitor Time (CT) pin is used to select between thetwo available reset time delays designed into each device and also to adjust the reset time delayby connecting a capacitor. A separate SENSE input pin and VDD pin allow for the redundancy soughtby high-reliability systems.

This device has a low typical quiescent current specification of 4.5 µA (typical).The TPS3703 is suitable for industrial applications and applications that require accurateundervoltage and overvoltage monitoring.
