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 minimum of 140msec
after VCC rises above the reset threshold. The YB1921
has an active-low RESET output. The output of the
YB1921 is guaranteed valid down to VCC=1V.
The YB1921 is optimized to reject fast transient
glitches on the VCC line. Low supply current of 18μA
(VCC=3.3V) makes these devices suitable for battery
powered applications.
