描述 Description

The DIODES™ AP25810LQ device is a USB Type-C® downstream-facing port (DFP) controller with an integrated 3A rated USB power switch. The AP25810LQ device monitors the USB Type-C configuration channel (CC) lines to determine when a USB device is attached. If an upstream-facing port (UFP) device is attached, the AP25810LQ applies power to the VBUS and communicates the selectable VBUS current-sourcing capability to the UFP via the pass-through CC line. If the UFP is attached using an electronically marked cable, the AP25810LQ also applies VCONN power to the cable CC pin. The device also identifies when USB Type-C audio or debug accessories are attached.

The AP25810LQ draws less than 0.7μA (typ) when no device is attached. Additional system power saving is achievable in the S4 and S5 system power states by using the output to disable the high-power 5V supply when no UFP is attached. In this mode, the device is capable of running from an auxiliary supply (AUX), which can be a lower-voltage supply (3.3V), typically powering the system μC in low-power states (S4 and S5).

The AP25810LQ 30mΩ power switch has two selectable fixed-current limits that align with the Type‑C current levels. The  output signals when the switch is in an overcurrent or overtemperature condition. The  output controls power management to multiple high-current Type-C ports in an environment where all ports cannot simultaneously provide high current (3A).

The AP25810LQ is available in a standard Green W-QFN3040-20 (Type A1) package with exposed PAD for improved thermal performance, and is RoHS-compliant.
