ADM6316CY29ARJZ-R7: Supervisory Circuit with Watchdog and Manual Reset in 5-Lead SOT-23
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 parts feature different combinations of watchdog input, manual reset input, and output stage configuration, as shown in Table 1.
Each part is available in a choice of 26 reset threshold options ranging from 2.5 V to 5 V in 100 mV increments. There are also four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms (minimum) and four watchdog timeout options of 6.3 ms, 102 ms, 1600 ms, and 25.6 sec (typical).
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ ADM6321/ADM6322 are available in 5-lead SOT-23 packages and typically consume only 3 μA, making them suitable for use in low power portable applications.
