MAXIM INTEGRATED / ANALOG DEVICES DS1232 MicroMonitor Chip

The DS1232 MicroMonitor™ chip is a versatile microprocessor supervisory device that halts and restarts an out-of-control microprocessor, ensuring stability during power transients. It monitors three critical conditions: power supply voltage (VCC), software execution via a watchdog timer, and external override through a pushbutton. The device features a precision temperature-compensated reference and comparator to detect out-of-tolerance VCC levels, generating an internal power fail signal that resets the microprocessor when needed. After power is restored, it maintains reset signals for at least 250 milliseconds to allow system stabilization. Additionally, it includes pushbutton reset control and an internal watchdog timer that activates a reset if the strobe input is not driven low before timeout. The compact 8-pin mini-DIP package makes it suitable for space-constrained applications. This component is ideal for power management in electronic systems, providing reliable microprocessor supervision without the need for discrete components.
