1. Key Features

The Automotive MP-A9_Rev1.0
(MP-A9_Rev1_SCH-29323_B2,
MP-A9_Rev1_LAY-29323_B2) wireless
charging TX demo is used to transfer power
wirelessly to a charged device. A charged device
can be any electronic device equipped with a
dedicated Qi wireless charging receiver.
The main parameters of the wireless charging
transmitter (WCT) are as follows:
• The input voltage ranges from 9 V DC to
16 V DC (automotive bat range).
• The input voltage can drop down to 6 V
DC level during the start-stop function.
• The nominal delivered power to the
receiver is 15 W (at the output of the
receiver) and can be compatible with 5W
receiver.
• Designed to meet the Qi 1.2.3
specification.
• Operation frequency: 125 kHz for Qi
devices.
