... Load Regulation: The change in output voltage for a change in load current at constant chip temperature. Quiescent Current: The part of the positive input current that does not contribute to the positive load current. The regulator ground lead current with no load. Current Limit: Peak current that can be delivered to the output. NCV8518 (continued) (-40°C ≤ T ≤ 150°C; 6.0 V ≤ ...

... Watchdog pulse and check its inputs to decide if it should resume normal operation or remain in sleep mode. The NCV8518 responds to the falling edge of the Watchdog signal, which it expects at least once during each Wakeup period. When the correct Watchdog signal is received, the Wakeup output is forced low. Other Watchdog pulses received within the same cycle are ignored ...
