USB PD Controller from Diodes Incorporated Supports Standard and Proprietary Protocols for Power Delivery in a Small Outline Package

PLANO, Texas–(BUSINESS WIRE)–Diodes Incorporated (Nasdaq: DIOD) today announced the introduction of
the AP43770 USB Type-C™ power delivery (PD) controller, a highly
integrated solution for implementing PD over USB in fixed and portable
devices, and offline power adapters. The AP43770 is well-suited to a
range of applications where USB PD is implemented, including AC
adapters, power hubs, battery banks, and USB PD converters. It features
an embedded microcontroller running firmware compliant with the latest
USB Type-C specification and USB PD Revision 3.0 V1.1. Support for
Qualcomm® Quick Charge™ (QC) 4/4+ is built into the device.
Additionally, the inclusion of QC3.0, QC2.0, and Battery Charging (BC)
revision 1.2 and other legacy protocols with auto-detection means that
backwards compatibility can be maintained with existing equipment.

The programmable power supply (PPS) feature, introduced with the latest
version of the USB PD specification, is also supported by the AP43770.
The PPS feature allows the output voltage to vary based on the load
requirements; this is communicated using a relevant augmented power data
object (APDO). Support for PPS with APDO is implemented in the AP43770
through a constant current and constant voltage (CC/CV) output driver
that is adjustable in 50mA steps up to 6A, and 20mV steps between 3V and
20V, respectively.

As USB PD has the potential to deliver high levels of power, the USB
eMarker feature is increasingly applied to active cables. The AP43770
includes the necessary support for eMarker technology, in order to
detect and identify cables before power is delivered. Cable compensation
is also supported.

When coupled with a suitable PWM controller, such as Diodes’ AP3108L,
the AP43770 provides a total PD solution. It also features up to 8kb of
OTP (for main firmware code) or MTP (for user configurable parameters).
MTP memory can be used to set up power specification and protocol
options to the manufacturer’s requirements.

The AP43770 is available in the space-saving TSSOP-16 package. Further
