ADM8320WCY29ARJZR7

ADM8320 is a supervisory circuit with watchdog and manual reset that monitor 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 present timeout period. A reset signal can also be asserted by an external push-button switch through a manual reset input. Application includes automotive infotainment, microprocessor systems computers, controllers, intelligent instruments, portable equipment.

• Manual reset input, low power consumption
