Product Overview
The device provides separate open-drain UV and OV outputs for undervoltage and overvoltage indication. Electrical characteristics include 6.0 µA typical supply current at VDD = 2 V, 7.0 µA typical supply current at VDD ≥ 5 V, and 300 nA maximum open-drain output leakage current under the listed pull-up conditions. Propagation delay is specified at 19 µs typical high-to-low and 35 µs typical low-to-high with VDD = 2 V, 2.5% input overdrive, and RPU = 10 kΩ.
TPS3702 is supplied in a SOT-6 (DDC) 6-pin package with nominal 2.90 mm × 1.60 mm body size. Recommended operating limits include 0 V to 6.5 V for SENSE and SET, 0 V to 18 V for UV and OV pins, and 2.2 kΩ to 10000 kΩ pull-up resistance. Applications include power rail window monitoring, undervoltage indication, overvoltage indication, and fixed-threshold supply supervision.
