Features, Applications

is an integrated IC for the wireless power transmitter. This device is composed of inverters for the coil drive, controller for the communication of the Qi compliant and demodulating circuit, GPIO, TCXO buffer, and I2C interface. BD57020MWV works as a controller in the wireless power transmitter based on the Qi compliant by using it with a general-purpose microcomputer. BD57020MWV is applied Qi ver.1.2 BPP / EPP (Baseline Power Profile / Extended Power Profile).

Input Power Supply Voltage Range: 5.3 V Input Adapter Voltage Range: 20 V Drive Frequency Range: to 205kHz Operating Temperature Range: to +85C


WPC Qi ver.1.2 BPP / EPP (Baseline Power Profile / Extended Power Profile) support. Half Bridge / Full Bridge inverter Foreign object detection GPIO 4CH I2C bus interface x 5.0mm UQFN package 40 pin

(Note 1) Derate by 26 mW/C when operating above Ta=25C (Mount x 1.6mm board with front and back layer heat radiation copper foil x 4.5 mm, second and third layer heat radiation copper foil x 74.2 mm). Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
