Detailed Product Description
Product Details
GENERAL DESCRIPTIONThe ADM823/ADM824/ADM825 are supervisory circuits that monitor 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 can also be asserted by an external pushbutton, through a manual reset input. The three parts feature different combinations of watchdog input, manual reset input, and output stage configuration, as shown in Table 1.
FEATURESPrecision 2.5 V to 5 V power supply monitor7 reset threshold options: 2.19 V to 4.63 V 140 ms (minimum) reset timeout Watchdog timer with 1.6 sec timeout (ADM823, ADM824) Manual reset input (ADM823, ADM825) Push-pull output stages RESET (ADM823) RESET, RESET (ADM824/ADM825) Low power consumption: 5 μA Guaranteed reset output valid to VCC = 1 V Power supply glitch immunity Specified over automotive temperature range 5-lead SC70 and SOT-23 packages
