DETAILED FUNCTIONAL DESCRIPTION
The MSP430BQ1010 operation can be classified into two main routines: power-up routine and main loop routine.
On power-up, the MSP430BQ1010 executes the power-up routine, which enables the AC Detect, initial Adapter
Detect check, and transmits signal strength, ID, and configuration packets to the transmitter (in the same
sequence). Table 1 shows packet information for each of the power-up routine packets.

Once the power-up routine is completed, the device enters the main loop routine. In the main loop routine, the
analog inputs are sampled every 32 ms and the control error packet is transmitted every 32 ms or 250 ms,
depending on whether the error calculated was a large error or a small error, respectively. Control error is the
percentage difference between the desired and actual rectifier output voltage that is sent to the transmitter by the
receiver to adjust the transmitter coil current.
Along with the control error packet, a power packet (see Table 2) that represents the received power or the
actual power is sent to the transmitter every 4 seconds during the main loop routine. The control error and the
actual power messages are calculated by the Control Error Packet and Power Packet generator block.

W = (VIN_DIV × ISET_SCALE) × 100 / 5 W
During the main loop routine, various protection features such as minimum load detect, overcurrent detect,
wireless disable, and termination detect are enabled. Appropriate actions are taken when any one of these
conditions is detected.
AC Detect
This block detects the presence of a wireless power signal during the power-up routine of MSP430BQ1010. This
feature is always enabled during the power-up routine. On device power-up, if the voltage at AC_DETECT pin is
less than VAC-DET-HI-THRESHOLD, the device waits until this voltage rises above VAC-DET-HI-THRESHOLD to proceed with
the rest of the power-up routine. If the voltage at AC_DETECT pin later falls below VAC-DET-LO-THRESHOLD during
the power-up routine, the device is reset and the execution goes back to comparing the voltage at AC_DETECT
pin against VAC-DET-HI-THRESHOLD.
