MWCT1000CFM

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 Freescale touch sensing technology or use periodically analogue PING (configurable by user) to detect a mobile device for charging while gaining super low standby power. The IC supports any low power guided positioning single coil power transmitter design (WPC types or customization) using operation frequency and duty cycle control by software based solutions. It features Foreign Object Detection (FOD) method to protect from overheating by misplaced metallic foreign objects. Typically used in any guided positioning single coil solution with frequency and duty cycle control.

• 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)
• Dynamic input power limit for limited input power supply
• FreeMASTER GUI tool to enable configuration, calibration and debugging
• Software based solution to provide maximum design freedom and product differentiation
• Low standby power (less than 25mW) by Freescale Touch technology
• Overvoltage/overcurrent/ overtemperature protection
