TC7763WBG
TOSHIBA CDMOS Integrated Silicon Monolithic Circuit
TC7763WBG
Qi Compliant Wireless Power Receiver Controller IC
1. Outline
The TC7763WBG is wireless power receiver (RX) IC compliant
to the Qi low power v1.1 standard of the Wireless Power
Consortium (WPC). The TC7763WBG includes a rectifier circuit,
a digital control circuit, a modulation circuit, a regulator circuit
which controls the supply voltage to the load, and a load switch
controller to detect and select an external power supply. A digital
control circuit realizes little heat generation and guarantees
voltage stabilization during load changes. The IC includes all RX
functions needed to construct a standalone wireless power system.
The integrated loadswitch driver for external loadswitch allows to
S-XFLGA28-0304-0.50-001
bypass the wireless power function when a USB or AC power source is connected to the mobile device.
2. Applications
Mobile communication devices (Smartphone, Featurephone, tablet), battery pack, mobile accessory etc.
