Monitoring Voltage Rails on Delfino with TPS3702 Reference Design

TIDA-00392

Design files

Overview

The C2000 Delfino microcontrollers' demand for a tight tolerance on both of its supply rails; this supervisory topology is designed to monitor the two voltage rails and assert a reset when either rail is not within its threshold. The two supervisors will monitor for both undervoltage and overvoltage conditions on each voltage rail; this layout is also less prone to asserting nuisance resets due to the user selectable options on the TPS3702 product family.

Features
  • High Threshold Accuracy
  • Threshold adjustable through SET pin
  • Internal Hysteresis: 0.55%, 1.0%

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
