ADM6316BX30ARJZ

监控电路 Watchdog w/ MR IC

Supervisory Circuits with Watchdog  and Manual Reset in 5-Lead SOT-23

GENERAL DESCRIPTION ADM6316BX30ARJZ

The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ ADM6321/ADM6322 are supervisory circuits 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 preset timeout period. A reset signal can also be asserted by an external push button through a manual reset input. The seven devices feature different combinations of watchdog input, manual reset input, and output stage configuration, as shown in Table 1.
