Kinetic Technologies KTE7200 Wireless Power Receiver

Kinetic Technologies KTE7200 Wireless Power Receiver is a robust WPC/Qi v1.2 standards compatible single-chip solution designed for low-power devices. This device is optimized for low-cost, low-power devices with small coils, low component count, and low-cost PCB designs. The KTE7200 exhibits a microcontroller-based design, optionally configurable by OTP memory, resistor programming features, and/or control via the I²C interface. This highly integrated wireless power receiver includes 8k ROM, 8k OTP memory, an LDO regulator with OVP/OCP/RCP, and precision-regulated DC output. Typical applications include earbud cases, mice, IoT devices and accessories, personal care products, toys, other battery-powered equipment, and battery-free devices using only wireless power.
