IC simplifies wireless charging

The DA4100 RF-transmit IC from Dialog Semiconductor simplifies the implementation of compact WattUp-based wireless power transmitter systems. This highly integrated system-on-chip is the result of a strategic partnership between Dialog Semiconductor and Energous, the developer of WattUp wire-free charging technology that provides over-the-air power at a distance.

Forming the core of a near-field WattUp transmitter system, the DA4100 integrates an ARM Cortex M0 processor, RF transmitter, power management, and DC/DC supply into a single 7×7-mm package. An embedded secure element allows two-way authentication with 128-bit encryption.
