PD 3.1 fast charge protocol chip inventory
PD 3.1 fast charge protocol
The PD 3.1 protocol standard has been launched for half a year, and Apple has also launched the first 140W fast charge that supports the PD 3.1 fast charge standard. With the increase in output power and the continuous expansion of the fast charging market, PD 3.1 fast charging technology has attracted the attention of the industry. Now that the PD 3.1 fast charging outlet has arrived, chip manufacturers are vying to launch the PD 3.1 protocol chip card bit terminal manufacturer supply chain, sharing the first wave of market dividends brought by the new PD 3.1 standard.
At present, chip manufacturers such as Infineon, Huinengtai, Injixin and Tiandeyu have taken the lead in launching fast-charging protocol chips that can meet the PD 3.1 standard application to seize market opportunities.
Infineon First Release of PD 3.1 Protocol Controller Chip
Two months after the release of the PD 3.1 protocol, Infineon released the world's first controller chip PMG1-S3 that supports the PD 3.1 protocol in Munich, Germany. At the same time, during the dismantling of Apple’s PD 3.1 140W fast charging by the electronic enthusiast network before, the editor found that Apple’s PD 3.1 fast charging products also use Infineon’s PD 3.1 protocol controller chip, but not PMG1- S3 is a protocol chip customized by Apple to Infineon.

PMG1-S3 is Infineon’s first-generation high-voltage microcontroller. According to Infineon’s official introduction, the chip supports PD 3.1 fast charging protocol with a maximum output power of 140W and can be applied to high-voltage and high-power up to 28V/5A Embedded system. PMG1-S3 has built-in Arm Cortex-M0+ processor, 256K large-capacity Flash and 32 KB SRAM, and general-purpose programming GPIO pins. In order to improve the operability of this chip, Infineon has added programmable analog and digital modules to it. Some smart modules and sensors can be integrated into the application through programming to improve the operability of the chip. At the same time, it supports AES, SHA1, and SHA2 chip encryption functions, reducing the risk of terminal products being copied, and protecting the intellectual property rights of developers. The firmware can also be updated and upgraded through the signature, thereby improving efficiency.
Huinengtai, which launched a complete PD 3.1 solution
Huinengtai is the only chip manufacturer in China to participate in the formulation of the PD3.1 standard. According to the official website, Huinengtai’s PD 3.1 product line has a layout in the three sub-fields of power supply end, power receiving end, and power supply cable. On November 19, a complete PD 3.1 solution from power supply to cable was launched.

HUSB311 is a control chip that complies with USB Type-C and PD 3.1 standards. By configuring the I2C port parameters, you can switch to three different working modes: USB PD 3.1 Source only, Sink only, and DRP at will to achieve USB Type-C Port power supply controls the functions of VCONN, USB Type-C CC control and sampling, and USB PD data transmission. The chip can meet 28V/5A 140W power supply and power demand under PD 3.1 protocol mode.

In terms of PD 3.1 cables, Huinengtai launched the eMarker chip HUSB332B that can be applied to PD 3.1 protocol cables. According to Huinengtai’s official website, HUSB332B is the industry’s first USB-IF PD 3.1 certified chip, which can meet PD3.1 EPR 240W power transmission and USB4 Gen3 40Gbps data transmission, and can be perfectly adapted to Type-C 2.1 with a full load power of 240W. Cable. At the same time, Huinengtai also launched the HUSB332A, which supports the USB 4 and Thunderbolt 3 data communication standards in addition to the PD 3.1 protocol. Both chips have a built-in program burning storage unit, and the connector or cable can be burned into the working program through the program burning software. In terms of chip packaging, Huinengtai provides this chip with DFN2×2-6L, DFN2×2-8L, DFN2×3-8L and WLCSP-6B in multiple different forms of packaging to meet the different circuit layout requirements of terminal manufacturers.
Yingjixin PD 3.1 Protocol Chip
Prior to this, Injixin launched the fast charging chip IP2736 that supports the latest standard fast charging protocol of PD 3.1, successfully cutting into the high-power fast charging track. IP2736 is a USB port fast charging protocol control chip that integrates multiple protocols. It supports PD2.0/3.1/PPS/EPR 28V, QC 5, FCP/SCP, AFC and other mainstream fast charging protocols. The chip is highly integrated. In addition, voltage reference, multi-standard voltage regulation, power management, and various circuit protection functions are implemented to reduce the use of components in chip peripheral circuits and provide terminal manufacturers with a more streamlined and compact fast charging solution.
In terms of voltage reference, it integrates programmable current and voltage loop control functions. The minimum step voltage is controlled to 10mV. In order to ensure the stability of charging efficiency, a line loss compensation function is also added. In terms of power management, the chip has built-in N-channel MOS tube drive and pressure difference detection functions. The pressure difference detection function can monitor the pressure difference between the G pole and the S pole in real time. When the pressure difference is too large, the MOS tube will be automatically turned off to avoid The short circuit of the MOS tube causes irreversible damage to the peripheral circuit, which further reduces the cost of equipment debugging.
Tiandeyu PD 3.1 multi-port fast charging protocol chip
Tiandeyu is a subsidiary of Foxconn and has been deeply involved in the field of fast charge protocol chips for many years. Tiandeyu has recently updated its fast charge products and released the PD 3.1 fast charge chip JD6622 that supports the latest protocol standards.

According to Fan Guangyao, deputy manager of Tiandeyu’s marketing project, this is a PD 3.1 fast charging solution that can be applied to a maximum output power of 140W. The chip supports dual C-port independent fast charging output. Through the intelligent deployment system, it can be reasonable The allocation of the power required for the output receiving terminal is expected to be officially launched on the market next year for terminal manufacturers to choose.
