USB Power and Charging Port Controllers
WT6615F
| 【 General Description 】 |
| The WT6615F is a highly integrated USB Power Delivery (PD) controller that supports USB PD 3.0 Programmable Power Supply (PPS) specification and Qualcomm® Quick ChargeTM 4.0 or Quick Charge 4+ technologies designed for USB Type-C® Downstream Facing Port (Source) charging applications such as power adapters, wall chargers, car chargers, power strip, power banks, and etc. |
| The WT6615F minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, and control circuits of blocking MOSFET, and an 8-bit MCU to allow small form factor and low BOM cost. It supports wide operation voltage range from 3V to 30V without the need of an external LDO. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data. |
| The WT6615F is certified by USB Implementers Forum (USB-IF) for USB Type-C PD (TID: 1080015) and by UL for Qualcomm Quick Charge 4+ (Certificate Number: 4788486761-2). |
