MWCT1101CLH

Wireless power transmitter controller with integrated digital demodulation. The device integrates all required functions for WPC Qi compliant wireless power transmitter design. It’s an intelligent device to work with touch sensing technology or use periodically analogue PING (configurable by user) to detect a mobile device for charging while gaining super low standby power. To maximize the design freedom and product differentiation, it supports any low power consumer power transmitter design (WPC A/B types or customization) using frequency and duty cycle control or rail voltage control or phase shift control by software based solution. It includes overvoltage/current/temperature protection, FOD method to protect from overheating by misplaced metallic foreign objects.

• Supports wide DC input voltage range starting from 4.2V, typically 5V, 12V and 19V
• Supports all types of receiver modulation strategies (AC capacitor, AC/DC resistor)
• Software based solution to provide maximum design freedom and product differentiation
• CAN/I2C/SCI/SPI interfaces for external communication purpose
