USB Type-C : Type-C Port Controller

LD6610

General Description
USB Power Delivery Controller Qualcomm® Quick Charge™ 4/4+ Controller 

The LD6610 is an USB Power Delivery (USB PD) Type-C controller in the secondary side for highly efficient and slim form factor off-line AC-DC design. An 8-bit MCU is embedded to handle PD protocol, policy engine and device policy manager with built-in Bi-phase Mark Coding (BMC) for USB PD communication or other proprietary protocols (e.g., QC2.0/QC3.0, QFN-16 and SOP-16 only).
To minimize external components, it integrates shunt regulator, voltage and current monitor and control circuit of blocking MOSFET. Build-in regulators provides 1.8V for MCU and peripherals to operate at single power supply from 3 to 20V.
