Mitsubishi M62030FP Datasheet
VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
GENERAL DESCRIPTION
The M62030FP is a voltage threshold detector designed for
detection of an input voltage/supply voltage and generation of
a system reset pulse for almost all logic circuits such as
microcontroller.
It contains a delay circuit which provides 200µs (typ) delay
and 4 modes of delays [25ms, 50ms, 100ms, 200ms (typ)] in
the input voltage detection type and in the supply voltage
detection type, respectively.
FEATURES
• Built-in 2 functional circuits for detecting voltage
• Built-in delay circuit to provide long delay time
(without external delay capacitors)
• Selectable 4 modes of delay time
[25msec, 50msec, 100msec, 200msec(typ)]
• Few external components
• Small 8-pin SOP package
