6 / 16 page ADM8316/ADM8318/ADM8319/ADM8320/ADM8321/ADM8322 Data Sheet Rev. 0 | Page 6 of 16 PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS Figure 3. ADM8316/ADM8320 Pin Configuration Table 3. ADM8316/ADM8320 Pin Function Descriptions Pin No. Mnemonic Description 1 RESET Active Low Reset Output. Asserted whenever VCC is below the reset threshold, VTH. This pin is a push-pull output stage for the ADM8316 and an open-drain output stage for the ADM8320. 2 GND Ground. 3 MR Manual Reset Input. This is an active low input that, when forced low for greater than the glitch filter time, generates a reset. It features a 75 kΩ internal pull-up resistor. 4 WDI Watchdog Input. Generates a reset if the logic level on the pin remains low or high for the duration of the watchdog timeout. The timer is cleared if a logic transition occurs on this pin or if a reset is generated. Leave this pin floating to disable the watchdog timer. 5 VCC Power Supply Voltage Being Monitored. Figure 4. ADM8318/ADM8321 Pin Configuration Table 4. ADM8318/ADM8321 Pin Function Descriptions Pin No. Mnemonic Description 1 RESET Active Low Reset Output. Asserted whenever VCC is below the reset threshold, VTH. This pin is a push-pull output stage for the ADM8318 and an open-drain output stage for the ADM8321. 2 GND Ground. 3 RESET Active High Push-Pull Reset Output. 4 WDI Watchdog Input. Generates a reset if the logic level on the pin remains low or high for the duration of the watchdog timeout. The timer is cleared if a logic transition occurs on this pin or if a reset is generated. Leave this pin floating to disable the watchdog timer. 5 VCC Power Supply Voltage Being Monitored. Figure 5. ADM8319/ADM8322 Pin Configuration Table 5. ADM8319/ADM8322 Pin Function Descriptions Pin No. Mnemonic Description 1 RESET Active low Reset Output. Asserted whenever VCC is below the reset threshold, VTH. This pin is a push-pull output stage for the ADM8319 and an open-drain output stage for the ADM8322. 2 GND Ground. 3 RESET Active High Push-Pull Reset Output. 4 MR Manual Reset Input. This is an active low input that, when forced low for greater than the glitch filter time, generates a reset. It features a 75 kΩ internal pull-up resistor. 5 VCC Power Supply Voltage Being Monitored.
