Product Summary
The ADM824SYRJZ is a supervisory circuit that monitors power supply voltage levels and code execution integrity in microprocessor-based systems. In addition to 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 of hte ADM824SYRJZ can also be asserted by an external push-button, through a manual reset input. The device features different combinations of watchdog input, manual reset input, and output stage configuration. The ADM824SYRJZ is available in a choice of seven reset threshold options ranging from 2.19 V to 4.63 V. The reset and watchdog timeout periods are fixed at 140 ms (minimum) and 1.6 sec (typical), respectively. The ADM824SYRJZ is available in 5-lead SC70 and SOT-23 packages and typically consume only 5 μA, making it suitable for use in low power, portable applications.
