Weltrend Semiconductor (TWSE: 2436) recently announced the launched of WT6617F, the Company’s first AEC-Q100 qualified USB PD controller for automotive-grade performance designed for automotive USB Type-C power source applications such as seat chargers, and infotainment unit chargers.

The WT6617F minimizes external components by integrating USB PD baseband PHY, Type-C detection, shunt regulator, voltage and current monitors, NMOS load switch driver and an 8-bit MCU to allow small form factor and low BOM cost. Wide operation voltage range (3V to 24V) supports PD 3.0 Programmable Power Supply (PPS) specification. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data.

Key features of Weltrend’s WT6617F automotive-grade USB PD controller include:
- USB Type-C and USB-PD
Supports USB BC1.2 DCP, Quick Charge 4 and Quick Charge 4+ (backward compatible Quick Charge 3.0 and Quick Charge 2.0)
- Built-in shunt regulator
- Programmable fault protections
- 10-bit ADC for voltage and current monitoring
- MCU
- Driver for NMOS load switch
- Built-in discharge MOS transistor
- Internal RC oscillator
- Internal VDD regulator
- General purpose I/Os
- Supports power saving mode
- Operating voltage range: 3V to 24V (30V tolerant)
- Package: 16-Pin QFN, 14-pin SOP AEC-Q100 Grade 1 Qualified (-40 to +125℃)
