The bq500212A is a 5V input single coil wireless power transmitter. The designer has several options regarding the design which we will cover in this presentation. The bq500212A eliminates the MSP430 used in previous designs to manage low power sleep mode. To reduce power during Standby, no RX on charging pad or charge complete 3.3V is removed from the bq500212A.

New Design used with bq500212A will only use Digital Ping. Digital Ping is a 75mS pulse that will power RX and gives it an opportunity to respond. Ping is sent at regular intervals based RC time constant no MSP430 used.
