S1F77200Y Series
S1F77200Y Series CMOS Voltage Detectors
DESCRIPTION
FEATURES
The S1F77200Y series products are non-adjusting volt-
age detectors being developed utilizing he base of the
CMOS silicon gate process.
• Full lineups: 19 types are prepared for the detection
range between 2.0V to 5.0V.
For the detection range from 0.8V to 2.5V, 7 types
are available (products designed for lower voltage
detection).
This voltage detector consists of the reference voltage
circuit, voltage comparator, hysteresis circuit and out-
put circuit, all operating on smaller current.
• Low operating current: Typ. 2.0 µA (VDD = 5.0V).
• Low operating voltage: 1.5V at minimum.
• Absolute maximum rated voltage: 15V maximum.
• Highly stable built-in reference voltage source: Typ.
1.0V.
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.
• Better temperature characteristics of output voltage:
Typ. -100ppm/°C.
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.

FUNCTIONAL DESCRIPTIONS
detection voltage (VDET) for the input voltage drop and
relief voltage (VREL) for the increased input voltage are
set based the following formula.
The S1F77200Y series has the circuit configuration as
shown in the figure below. For the detection, divided
potential (VREG) across the resistors inserted across the
power supply and the reference voltage (VREF) gener-
ated on the IC are entered to the voltage comparator.
Since the voltage comparator is designed to detect a tar-
get voltage even when potential difference between
VREG and Vref minute, hysteresis is added so that the
comparator may not fail due to noise on the power sup-
ply and such. In the example shown in the figure below,

Note: The above input/output characteristics assumes that the pull up resistor is connected to the output pin for
the S1F77200Y series. For the S1F77220 series, it assumes that the pull down resistor is connected
between the OUT and VDD pins.
If the input voltage that is applied between VDD and VSS terminals drops below the lower limit of voltage
for IC operation, the output condition of the OUT terminal may become unsteady.
Ensure to prevent problems from occurring in circuit operation.

PRECAUTIONS
Short cut current on the S1F77210 (CMOS output voltage detector)
Since the S1F77200Y series employs CMOS output, as an input voltage nears the detection voltage range, short cut
current is flown between VDD and VSS. The short cut current is voltage sensitive, and approximately 2 mA flows at
5V level or so (our products are not check for short cut current after volume production has been started).
Although duration of the short cut current depends on operating conditions (such as type the circuit used and supply
impedance), normally it is assumed to continue several usec to several dozens of usec.
If a load with high impedance is inserted across the power supply, oscillation can be introduced by the short cut
current. In order to reject this trouble, the following measures should be considered:
(1) Reduce the resistance value.
(2) Insert a capacitor.
(3) Replace with the S1F77200Y series (it employs N-channel open drain approach).
