DESCRIPTION
The S1F77200Y series products are non-adjusting volt-
age detectors being developed utilizing he base of the
CMOS silicon gate process.
This voltage detector consists of the reference voltage
circuit, voltage comparator, hysteresis circuit and out-
put circuit, all operating on smaller current.
A voltage range to be detected is internally set on re-
spective detectors. A wide variety of our standard prod-
ucts are grouped as shown below according to the out-
put format employed for the voltage detector output pin.
The S1F77200Y series employs N-channel open drain
output approach. And the S1F77210Y series and S1F
77220Y series employ the CMOS output and P-channel
output, respectively.
The package used is the SOT89-3 pin plastic package.
Our voltage detectors are used for determining battery
life, and also for monitoring supply voltage fed to mi-
crocomputers and LSI systems.
FEATURES
