What are the key features of UPD350DT/Q8X?
- USB Type-C Power Delivery 3.0 compliance with full port controller functionality in a single IC
- SPI and I2C host interfaces at up to 48 MHz clock for fast system integration with MCUs and PMICs
- Ultra-low 15 mA maximum supply current enables efficient power management in battery systems
- Compact 28-pin 4x4 mm QFN package with exposed thermal slug for dense, heat-managed layouts
- Automotive-grade TS 16949 screening for use in high-reliability and in-vehicle USB charging ports
What is UPD350DT/Q8X used for?
The UPD350DT/Q8X is designed for laptop docking stations, AC adapters, and USB-C charging hubs where a dedicated PD 3.0 port controller offloads negotiation from the host processor via SPI or I2C at 48 MHz. Its 15 mA low current draw makes it suitable for power-efficient USB-C implementations in portable devices and tablets. Automotive USB charging ports benefit from its TS 16949 screening and robust PD 3.0 compliance in a compact 28-pin QFN form factor.

Frequently Asked Questions
What USB Power Delivery version does the UPD350DT/Q8X support, and at what clock speed does it operate?
The UPD350DT/Q8X supports USB Type-C Power Delivery 3.0 and operates with a maximum clock frequency of 48 MHz, enabling fast PD message processing through its SPI and I2C host interfaces. Its 15 mA supply current keeps the port controller's contribution to overall system power budget minimal, making it ideal for portable device charging applications.
How does the SPI interface of UPD350DT/Q8X benefit embedded system integration?
The SPI interface allows the UPD350DT/Q8X to communicate with host MCUs and PMICs at up to 48 MHz, enabling low-latency PD 3.0 negotiation data exchange without tying up slower I2C buses. This is advantageous in designs where the MCU manages multiple peripherals simultaneously, as the high-speed SPI offloads USB-C power contract management to the dedicated UPD350 controller across 28-pin QFN-connected boards.
For which automotive or industrial applications is the UPD350DT/Q8X screening level appropriate?
The UPD350DT/Q8X is screened to TS 16949 automotive quality standards, making it suitable for in-vehicle USB Type-C charging ports, infotainment systems, and industrial USB-C docking stations that require documented manufacturing process control. Its 28-pin QFN package with heat slug and 15 mA current draw support reliable long-life operation in temperature-cycling automotive environments.
How does the UPD350DT/Q8X compare to a discrete USB-C CC pin solution for PD 3.0 port control?
Unlike a discrete solution that requires separate CC logic, protection, and a microcontroller firmware stack to implement PD 3.0, the UPD350DT/Q8X integrates the full PD 3.0 port controller in a single 28-pin QFN, reducing BOM component count, PCB area, and firmware development time. Its 48 MHz clock and 15 mA consumption also deliver faster negotiation with lower system power overhead than multi-chip alternatives.
