TPS3702-Q1 SBVS261C – APRIL 2015 – REVISED MARCH 2024 TPS3702-Q1 Automotive High-Accuracy Over and Undervoltage Monitoring 1 Features AEC-Q100 Qualified: – Device temperature grade 1: –40°C to 125°C ambient operating temperature – Device HBM ESD classification level 2 – Device CDM ESD classification level C4B Input Voltage Range: 2V to 18V High threshold accuracy: – 0.25% (typical) – 0.9% (–40°C to 125°C) Fixed window thresholds optimized for nominal rails between 1V and 5V Open-drain outputs for overvoltage and undervoltage indication Internal glitch immunity Threshold adjust using the SET pin Low quiescent current: 7µA (typical) Internal threshold hysteresis: 0.55%, 1.0% SOT-6 package 2 Applications Automotive safety applications Infotainment FPGA and ASIC applications DSP-based systems Front cameras Rear-View cameras Automotive radar systems Nominal Monitored Rail Up to 5 V Up to 18 V Up to 6.5 V TPS3702 R2 SENSE UV VDD SET GND OV R1 VDD RST µP NMI 3 Description The TPS3702-Q1 is an integrated overvoltage and undervoltage window voltage detector in a small SOT-6 package. This highly accurate voltage detector is an excellent choice 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 the normal range of operation. Internal glitch immunity and noise filters further elimina...
