YB1921 3-Pin Microprocessor Reset Monitor Introduction The YB1921 is a cost-effective system supervisor Integrated Circuit (IC) designed to monitor VCC in digital and mixed signal systems and provide a warning signal when the system power supply is out of working range, and a reset signal to the host processor when necessary.

No external components are required.

The reset output is driven active within 20μsec of VCC falling through the reset voltage threshold.

Reset is maintained active for a mi
