S1F77200Y Series S1F77200Y Series CMOS Voltage Detectors FEATURES The S1F77200Y series products are non-adjusting voltage 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 output circuit, all operating on smaller current. A voltage range to be detected is internally set on respective detectors. A wide variety of our standard products are grouped as shown below according to the output 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 microcomputers and LSI systems. * 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). * Low operating current: Typ. 2.0 A (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. * Better temperature characteristics of output voltage: Typ. -100ppm/C.

For the detection, divided potential (VREG) across the resistors inserted across the power supply and the reference voltage (VREF) generated on the IC are entered to the voltage comparator. Since the voltage comparator is designed to detect a target 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 supply and such. In the example shown in the figure below, detection voltage (VDET) for the input voltage drop and relief voltage (VREL) for the increased input voltage are set based the following formula. Detection voltage: VDET = R1+R2+R3 * VREF R2+R3 Relief voltage: R1+R2+R3 * VREF R3 VREL = VDD (2pin) R1 (VREG) + T R2 -- T OUT (1pin) VREF R3 VSS (3pin) 5-4 EPSON S1F70000 Series Technical Manual S1F77200Y Series The following figures show the input and output characteristics of the S1F77200Y series.

For the S1F77220 series, it assumes that the pull down resistor is connected between the OUT and V DD 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.

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). S1F 77210Y 5-22 EPSON S1F70000 Series Technical Manual
