Product Description

The CM3400 is a universal supply voltage supervisory (SVS) controller for critical power monitoring and power sequencing applications. During an initial power-up, both complimentary outputs (RESET, RESET) remain active. Once the supply voltage being monitored exceeds the user programmed reset threshold, the outputs will remain active for an additional timeout interval which is also user controlled. Both outputs become inactive once the delay interval has expired.
