ADM8316WDZ30ARJZR7

ADM8316WDZ30ARJZR7 is a supervisory circuit that monitors power supply voltage levels and code execution integrity in microprocessor-based systems. As well as providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by an external push-button switch through a manual reset input. Applications include automotive infotainment, microprocessor systems, computers, controllers, intelligent instruments, portable equipment.

• Manual reset input, multiple reset output options, low power consumption
