When VDRAIN drops below VPG, the PWRGD sink current is turned off and a 6.5k resistor is connected between PWRGD and DRAIN, allowing the module’s pull- up current to pull the enable pin high and turn on the module. PWRGD/PWRGD (Pin 1): Power Good Output Pin. This pin will toggle when VDRAIN is within VPG of VEE. This pin can be connected directly to the enable pin of a power module. When the DRAIN pin of the LT1640AL is above VEE by more than VPG, the PWRGD pin will be high impedance, allowing the pull-up current of the module’s enable pin to pull the pin high and turn the module off. When VDRAIN drops below VPG, the PWRGD pin sinks current to VEE, pulling the enable pin low and turning on the module. PI FU CTIO S TYPICAL PERFOR A CE CHARACTERISTICS |
