ML7630
ML7630 is 13.56MHz wireless charging Rx LSI manufactured by LAPIS.
Overview
The ML7630 is a wireless charging Rx LSI using 13.56MHz carrier frequency, which enables to receive 200m W power wirelessly from a Tx device using the ML7631. The ML7630 also supports the NFC Forum Type3 TAG functions, and a TAG data is read out by the NFC readers including smartphones and tablets. The ML7630 is equipped with an I2C slave port for host interface and a 10bit SA-ADC for measuring output current to control charging current by software. This is an ideal solution for small rechargeable devices such as headset, ear-pads and wearables.
