ADM6823 Low Voltage Supervisory Circuits with
Watchdog and Manual Reset in 5-Lead SOT-23
The ADM6823 is available in a 5-lead SOT-23 package and typically consumes only 7 μA, making it suitable for use in low power, portable applications.
Applications
The ADM6823 is 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 means of an external push-button through a manual reset input. The part is available in nine reset threshold options, ranging from 1.58 V to 4.63 V. The reset and watchdog timeout periods are fixed at 140 ms (minimum) and 1.6 sec (typical), respectively.
