USB Power Delivery Controller
The LD6617 is a highly integrated USB power delivery (USB PD) controller that supports USB PD 3.1 SPR & EPR 28V/36V specification.
The IC is especially designed for USB type-C power source applications such as power adapters, wall chargers, car chargers, etc.
An 8-bit MCU is embedded to handle PD protocol and device policy manager with built-in bi-phase mark coding (BMC) PHY
for USB PD 3.1 SPR & EPR 28V/36V specification or other proprietary protocols (e.g. QC2.0/QC3.0).
As expected, the power noise will be increase, when a device will provide more high power due to the support of USB PD 3.1.
The LD6617 has an optimized BMC physical (PHY) which can implement communication by differential signal to efficaciously
prevent power noise.
To minimize external components, the LD6617 integrates optimized BMC PHY, blocking N-channel MOSFET driver,
a voltage/current monitor, and controller.
The 3.3V to 45V wide operation voltage enables the LD6617 to support USB PD 3.1 SPR & EPR 28V/36V specification.
The IC is available in SMD. LD6617 ?? in QFN-16 package.
