• Manufacturer Part Number: S1F7760X
• Description: Power Supply Ic
• Manufacturer: Epson Electronics America, Inc.

1. DESCRIPTION
S1F77600 Series comprises high-accuracy, low-consumption low-voltage detectors which work at a low voltage.
Output is guaranteed until supply voltage reaches 0V. They are ICs used to prevent liquid leakage of a dry cell
by detecting the voltage drop of power supply of two cells connected in series. The internal circuits of the ICs
consist of reference voltage circuits, comparators, resistances for detecting voltage, hysteresis circuits,
output-securing circuits (forced output Hi-Z) and output transistors.
Detection voltage is of non-adjustment type, fixed inside the IC at high accuracy.
Output form is selectable from P-ch open drain and N-ch open drain.
The package is comprised of SOT89-3 pin and SON-6 pin (under development).
These ICs are best suited to the dry-cell liquid leakage prevention/protection circuit of a portable product which
uses power supply of two dry cells connected in series.
