Connected to a microcontroller, the new IC realizes a wireless power transmitter system compliant with Qi[1], the standard defined by the Wireless Power Consortium (WPC). Toshiba’s original cutting-edge CD-0.13 process realizes a small package and high efficiency, making system integration easy while securing a transmitter system with a small footprint. A 15W wireless transmitter formed with the new IC will recharge devices quickly, at a rate equal to or shorter than wired chargers. The IC is suitable for use in wide range of applications including mobile devices, such as smartphones and tablets, and industrial devices.
Wireless transmitters that use the new IC will be compatible with 5W receiver systems that use Toshiba's 5W receiver IC, "TC7764WBG,” and 10W receiver systems that use the “TC7765WBG” 10W receiver IC, both of which are in mass production. In combination with a 15W wireless receiver control IC “TC7766WBG” compliant with the Qi v1.2 standard, the wireless system can receive up to 15W power.
Main features
- WPC Qi v1.2 compliant (in combination with a microcontroller)
- Full-bridge gate driver (also compatible with half-bridge): 1ch
- Built in LPF[2] for recovery of ASK signal
- Built in LDO (3.3V output)
