MITSUBISHI<STD-LINEAR> VOLTAGE DETECTING, SYSTEM RESETTING IC M62032AFP BLOCK DIAGRAM GENERAL DESCRIPTION The M62032AFP is an IC for detection of two different input voltages to reset almost all logic circuits including MCU. It contains a delay circuit with which any delay time can be obtained only by adding an external capacitor. The IC is widely applicable to a battery check circuit, a level detection circuit, a waveform shaping circuit, etc.

MITSUBISHI<STD-LINEAR> VOLTAGE DETECTING, SYSTEM RESETTING IC M62032AFP AN EXAMPLE OF THE APPLICATION CIRCUIT 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.
