AP43761 document number: ds 38 416 rev. 3 - 2 4 of 8 www.diodes.com march 2018 ? diodes incorporated AP43761 new product o peration description overall introduction the AP43761 provides configure channels cc (cc1 and cc2) to control vbus output to u sb type - c port. cc1 and cc2, are used to detect attachment or detachment of usb type - c port, establish or cancel the connection of dfp and ufp. configur e channels control logic t here is 330 a constant current generated on cc1/cc2 pin. when ufp with a spe cified resistance (rd = 5.1k ? ) to gnd in cc pin is connected to dfp, about 1.683v voltage which is in the voltage range of v lrd3a (0.8v) and v hrd3a (2.6v) will be detected in one of cc pin of AP43761 . after the valid t cc _ debounce time (150ms), the AP43761 will turn on the internal pm osfet to delivery power via vbus pin ; o n the contrary , if no ufp is connected to dfp or other circumstances, none of the v cc1 and v cc2 voltage is in the voltage range of v lrd3a (0.8v) and v hrd3a (2.6v), after the valid t pd _ debounce t ime (15m s ), the ap437 61 will turn off the internal pmosfet to prevent delivering power from v bus pin . table 1. vbus output logic cc1 voltage cc2 voltage vbus output v lrd3a < v cc1 < v hrd3a don't care on don't care v lrd3a < v cc2 < v hrd3a v cc1 < v lrd3a or v cc1 > v hrd3a v cc2 < v lrd3a or v cc2 > v hrd3a off w hen the internal pmosfet of AP43761 is turned on, 3a current capacity can be achieved. bleeding resistance configuration when the detachment of ufp is detected, AP43761 will turn off the internal pmosfet to prevent delivering power from v bus pin . in order to make sure that the vbus voltage drops to vsafe0v (vsafe0v is vbus 0 volts as defined by the usb power delivery specification) within 650m s , a vbus bleeding resistance (r lk ) is placed between vbus and gnd of us b type - c port (see typical applications circuit part). the minimum value of r lk should be 72.4k ? .
