This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum ratings for extended periods of time may affect device reliability. ORDERING GUIDE Temperature Package Package Model Range Description Option ADM9690AR –40 °C to +85°C 8-Lead Narrow SO-8 Body SOIC PIN FUNCTION DESCRIPTIONS Mnemonic Function VCC Power Supply Input; +5 V. VMON Voltage Monitoring Input. GND 0 V. Ground reference for all signals. RESET(1) Logic Output. RESET(1) goes low if VMON falls below the Reset Threshold or the Watch- dog timer is not serviced within its timeout period. The reset threshold is typically 4.4 V for the ADM9690. RESET(1) remains low for 50 ms after VCC returns above the thresh- old. RESET(1) also goes low for 50 ms if the Watchdog Timer is not serviced within its timeout period. RESET(2) Logic Output. RESET(2) goes low simulta- neously with RESET(1) but remains low for an additional 10 ms. WDI Watchdog Input. If an edge is not detected on WDI within the selectable watchdog timeout period, RESET(1) and RESET(2) are forced low for their respective timeout periods. The watchdog timer restarts with each positive or negative going transition on the WDI line. Following a reset it is restarted when RESET(1) goes inactive (high). The Watch- dog Timer may be disabled if WDI is left floating or is driven to midsupply. SEL1, 2 Watchdog Timeout selection inputs. Refer to Table I.
