ON Semiconductor Announces New NCP1232 Microprocessor Monitor

ON Semiconductor LLC (Phoenix, AZ) has announced the addition of a microprocessor monitor to its sizeable power-management portfolio. The NCP1232 is a fully integrated microprocessor supervisor that safeguards processor sanity. It is designed for applications that require critical microprocessor power monitoring and provides three vital conditions for a microprocessor.

The NCP1232 has a precision power on/off reset control that halts and restarts an out-of-control processor, a programmable watchdog timer that holds a microprocessor in check during power transients and an external reset override that automatically restarts the microprocessor after a power failure. The on/off reset control ensures that the system and the power supply have time to stabilize by holding the microprocessor in a reset state for a minimum of 250msec after the supply voltage is within tolerance. This feature provides a power-on reset as power is applied, and detects intolerance in the supply voltage-preventing the system from operating in an unsafe environment.
