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.
FEATURES
• A small number of external components
• Built-in 2 input voltage detection circuits
• Wide supply voltage range ............... 2 to 10V
• Small 8-pin package
• Open collector output
APPLICATION
Reset circuit of MPU, MCU and logic
RECOMMENDED OPERATING CONDITION
Supply voltage range ......................... 2 to 10V
