Overview
The TPS3703A5180DSERQ1 is an integrated overvoltage (OV) and undervoltage (UV) monitor or reset IC produced by Texas Instruments. This device is designed for systems operating on low-voltage supply rails with narrow margin supply tolerances. It is highly accurate and features internal glitch immunity and noise filters to prevent false reset signals. The TPS3703A5180DSERQ1 is packaged in a 6-pin WSON (1.5 mm x 1.5 mm) package, making it one of the industry’s smallest solutions for voltage supervision. It is AEC-Q100 Grade 1 qualified, making it suitable for automotive applications.
