The TPS3703 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 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 is suitable for industrial applications and applications that require accurate undervoltage and overvoltage monitoring.
