AP53782DKZ-13-FA01

The AP53782DKZ-13-FA01 is a USB Type-C PD 3.1 dual-role-port (DRP) controller from Diodes for EPR designs up to 28 V and 140 W where a host processor must supervise power policy. It adds an I2C interface to a host MCU, enabling dynamic power profiles and intelligent power management that the resistor-only configuration of its sibling AP53781 cannot provide - for example re-balancing port budgets in multi-port chargers, docks and automotive hubs as devices attach and detach. The CC pins withstand 34 V for short-to-VBUS protection, and dead-battery operation is supported. The FA01 suffix denotes the standard firmware build; the package is a W-QFN4040-24 Type A1 with MSL 1 handling. Selection advice: the larger 24-pin package and host firmware effort only pay off when profiles must change at runtime; for fixed-profile ports, the smaller AP53781DMZ16-13-FA01 is the simpler and cheaper route, so confirm which behaviour your product specification actually requires before ordering.
