CY2332P
Enhanced Cost-Effective USB PD3.1 SPR Protocol Controller
Description
The CY2332P, an enhanced USB Type-C Power Delivery (PD) protocol controller, is ideally targeted for cost-effective USB-Type-C adapters and chargers. It is in full compliance with USB Power Delivery (PD) specification Rev3.1 SPR with certificated TID: 8180, including 25W to 100W fixed PDO, programmable power supply (PPS) and Qualcomm QC2.0/3.0/4/4+ protocol supports.
With the preloaded 8 power profiles in the CY2332P, system manufacturers could easily select a desired power profile for Constant Voltage (CV) and Constant Current (CC) control through a single resistor attached to the relevant pin (Pin 7 – PDO_S) of the CY2332P to meet output power requirements of a charger or adaptor. Not only does this approach saves after-shipment extra OTP (One-Time-Programmable) programming cost of the PD Decoder used in different power profile applications, but it also greatly simplifies inventory management of PD decoder chips for various output power chargers.
The CY2332P provides robust protection scheme with built-in OVP/UVP/OCP/SCP features. The CC1/CC2-short-to-VBUS protection is up to 28V for larger voltage and output power applications.

Typical Applications Circuit
The CY2332P supports. 8 power profiles of PD3.1 SPR, ranging from 25W to 100W and 3.3V to 21V PPS, have been preloaded in the OTP ROM of the CY2332P. The system designer can select a suitable power profile from Table 1 by connecting the corresponding 1% precision resistor to PDO_S pin (Pin 7).
Figure 1 shows a 25W CY2332P-based PD3.1 SPR charger. Connecting a 5.1KΩ RPDO_S from PDO_S pin (Pin 7) to the ground, the CY2332P is configured into a 25W power profile. Figure 2 illustrates a 65W ACF PD3.1 SPR charger with a 52KΩ RPDO_S attached to PDO_S pin (Pin 7).
This preloaded power profile at OTP approach could simplify charger manufacturing process and cost, as no need for extra OTP programming for the PD decoders, which significantly eases inventory management for PD decoder chips.
