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 200s (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.

EXAMPLE OF APPLICATION CIRCUIT
1) The application to microprocessor system
Note 1. The Input voltage detection type can be used as the voltage supervisor of microprocessor system
like the following circuit.
In this case, a detection power supply voltage is approximately 1.25 x (R1+R2)/ R2 (v).
The detecting supply voltage can be set between 2V and 10V.
Note 2. The detecting voltage can be adjusted by changing R1 and/or R2 in the following circuit.
The detection accuracy is 4%.
Note 3. It has a delay capacitor and the delay time is about 200s.

2) The Variable setup time type
Note 1. A delay time of the
supply voltage detection type can be set to one among 25ms, 50ms, 100ms and
200ms by the combination of pin 1 and pin 3.
Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable, but
there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury,
fire or property damage. Remember to give due consideration to safety when making your circuit design,in order to prevent
fires from spreading, redundancy, malfunction or other mishap.
