Supply/Recycle Hynetek HUSB252 USB Type-C PD DRP Controller With MCU

Shenzhen Mingjiada Electronics Co., Ltd. is a professional distributor of electronic components, now introducing the Hynetek HUSB252 USB Type-C PD DRP controller chip with MCU to its customers.

The HUSB252 supports bidirectional power delivery up to 100W and is fully compliant with the USB PD 3.1 specification. It further incorporates an integrated MCU with 16KB EEPROM.

This HUSB252 chip enables developers to customise charging strategies through secondary programming, facilitating the creation of diverse product forms ranging from simple power banks to complex workstation extensions.

【Chip Pioneer: Core Overview of HUSB252】

The HUSB252 is a high-performance USB Type-C DRP controller designed to address the complex power management and data transfer demands of modern electronics.

This chip supports bidirectional power transfer up to 100W, functioning as both a power source and power sink. Its integrated MCU with MTP memory provides exceptional flexibility and programmability.

In terms of protocol compatibility, the HUSB252 sets an industry benchmark. It fully supports the latest USB PD 3.1 specification and is compatible with multiple fast-charging protocols, including BC1.2, QC2.0/3.0, AFC, FCP, SCP, and the domestically prevalent UFCS integrated fast-charging protocol.

Notably, the HUSB252 incorporates an internal N-MOSFET driver. This eliminates the need for customers to design complex driver circuits, allowing direct control of external MOSFETs and significantly simplifying system design.

The HUSB252 incorporates comprehensive fault protection mechanisms, including overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), overtemperature protection (OTP), undervoltage protection (UVP), and thermal shutdown protection.

For communication interfaces, the chip integrates I2C and UART modules, facilitating data exchange and status monitoring with other system components.

【HUSB252 Applications: From Rapid Charging to Smart Display】

The HUSB252 chip finds extensive application across virtually all devices requiring Type-C interface power negotiation and data transmission.

In bidirectional fast charging, the HUSB252 enables flexible power role switching for laptops, tablets, power banks, and similar devices. When sufficiently charged, these devices can act as power sources for others; when depleted, they can rapidly recharge as power recipients.

Within display applications, the HUSB252's single-chip Type-C-to-DP solution offers a streamlined and efficient interface conversion. This solution requires only a single HUSB252 chip and minimal peripheral components to complete the full conversion from Type-C to DP, supporting both video signal transmission and power management.

The HUSB252 also incorporates dead battery functionality. Even when a device's battery is completely depleted, it can establish a connection with a power source and receive power supply, resolving the predicament where devices cannot charge when utterly drained.
