Supervisors
ams supervisors offer high accuracy and low power consumption. In battery-powered systems in particular, the supply must be monitored in order to perform safe start-up and shut-down operations. For multi-supply applications, power monitoring is essential for safe operation. The ams portfolio of supervisory products provides a comprehensive choice of functions including watchdog, manual reset, and dual, triple and quad voltage supervisors.
