1. DESCRIPTION
1. DESCRIPTION
The S1F772*1Y series is a nonadjustable voltage detector that was developed using the CMOS silicon-gate
process.
It consists of four major components: reference voltage circuit with low current consumption, voltage
comparator, hysteresis circuit, and output circuit.
This series, with the detecting voltage internally fixed, provides various standard products, which are classified
into the following two types depending on the output mode of voltage detector output pins:
The S1F77201Y series is an N channel open drain output product; the S1F77211Y series is a CMOS output
product.
The package is an SOT89-3pin plastic package.
This series also has functions that detects a battery life and monitors power voltage supplied to microcomputer
and LSI systems.
2. FEATURES
• Low current consumption:
Typ. 4.0µA
• Allowable low voltage:
Min. 1.5V
• Absolute maximum rated voltage:
Max. 22V
• High-stable reference voltage supply built-in: Typ. 1.0V
