DESCRIPTION

The bq500210 is a second generation Wireless Power dedicated digital controller that integrates the logic

functions required to control Wireless Power Transfer in a single channel WPC compliant contactless charging

base station. The bq500210 is an intelligent device that periodically pings the surrounding environment for

available devices to be powered, monitors all communication from the device being wirelessly powered, and

adjusts power applied to the transmitter coil per feedback received from the powered device. The bq500210 also

manages the fault conditions associated with the power transfer and controls the operating modes status

indicator. The bq500210 supports improved Parasitic Metal Object Detection (PMOD). The controller in real time

analyzes the efficiency of the established power transfer using Rectified Power Packets and protects itself and

the power receiver from excessive power loss and heat associated with parasitic metal objects placed in the

power transfer path.

The bq500210 is available in an area saving 48-pin, 7mm x 7mm QFN package and operates over a temperature

range from –40°C to 110°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.

Both coils have ferrite shields as part of their structures to even further maximize field coupling.

bq500210 SLUSAL8C – JUNE 2011 – REVISED SEPTEMBER 2012 www.ti.com Thermal Protection The bq500210 can provide thermal protection to the transmitter. An external NTC resistor can be placed in the most thermally challenged area, which usually is the center of the transmitting coil, and connected between the dedicated pin 2 and GND. The threshold on pin 2 is set to 1.00V. The NTC resistor and the resistor from pin 2 to VCC create a temperature sensitive divider.

bq500210 www.ti.com SLUSAL8C – JUNE 2011 – REVISED SEPTEMBER 2012 In some battery charging applications there is a benefit to continue the charging process in trickle charge mode to top off the battery. There are several information packets in the WPC specification related to the levels of battery charge – Charge Status. The bq500210 uses these commands in association with some of the LED modes described in Table 2 to enable the top-off charging pattern.
