Integrated over / under-voltage window detector in a SOT-6 package

This post is sponsored by Texas Instruments. The Texas Instruments (TI) TPS3702 is an integrated over-voltage and under-voltage window detector in a small SOT-6 package. The highly-accuracy voltage monitor is ideal for systems that operate on low-voltage supply rails and have narrow margin supply tolerances. Low threshold hysteresis options of 0.55% and 1.0% 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 TPS3702 does not require any external resistors for setting over-voltage and under-voltage reset thresholds, which further increases overall accuracy and reduces solution size and cost. The SET pin is used to select between the two available threshold voltages designed into each device. A separate SENSE input pin and VDD pin allow for the redundancy sought by safety-critical and high-reliability systems. This device also features independent reset outputs for the OV and UV pins; as a result of the open-drain configuration, UV and OV can be tied together. This device has a low typical quiescent current specification of 7µA and is qualified for use over the industrial temperature range of –40C to 125C.
