Qi 1.1 compatible wireless charging Ics

In last week, two new wireless power ICs compatible with Qi low-power specifications version 1.1 were announced. Toshiba America Electronic Components, Inc., (TAEC) has announced TB6865FG power transmitter and TC7763WBG receiver chipset to handle 5 -watt power transfer and is compatible with the Qi low-power specifications version 1.1 standards developed by Wireless Power Consortium (WPC). The TB6865FG integrates an MCU and can drive 4 external MOSFET H Bridges of 4 coils for a free positioning architecture supporting two mobile devices. The TC7763WBG receiver combines modulation and control circuitry with a rectifier power pickup, built-in Linear Dropout Regulator (LDO) and circuit protection functions. The transmitter IC is housed in a LQFP-100 14x14mm package and the receiver IC is supplied in a compact WCSP-28 2.4mm x 3.67mm x 0.5mm package. The TAEC power transmitter and receiver chipset, TB6865FG and TB7763WBG, is currently sampling and the sample price of the TB6865FG power transmitter is $7.00 and the TB7763WBG receiver is $3.50, announced by TAEC. Another expert of wireless power ICs Integrated Device Technology has also announced the Qi-compliant single-chip wireless power transmitter solution supporting a 5V input. The IDTP9038 is a single-chip wireless power transmitter IC compatible with the Wireless Power Consortium (WPC) 1.1 “Qi” standard for ...
