ADM6316DZ26ARJZ-R7 IC SUPERVISOR 1 CHANNEL SOT23-5 Analog Devices Inc.

 

GENERAL DESCRIPTION

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.
