Wireless Power Receiver for
Low Power Applications P9222-R
Datasheet Description Features The P9222-R is an integrated single-chip wireless power receiver
IC (Rx) for up to 5W applications. The device receives an AC power
signal from a wireless power transmitter, such as the P9235A-RB
WPC Qi BPP Wireless Transmitter IC, and converts it to a rectified
output voltage, which can be used to power devices or supply the
battery charger input in a wide range of wireless power
applications. The receiver (Rx) integrates a high-efficiency
synchronous full bridge rectifier (SFBR) and control circuits used to
send message packets to the transmitter (Tx) in order to optimize
power delivery.  Ultra-compact, efficient wireless power receiver for up to 5W applications  WPC 1.2.4 Qi Baseline Power Profile (BPP) compatible
 Optimized light load efficiency for low power applications
 Ping detection for reduced power consumption at end of

 The P9222-R is highly efficient at light loads and very well-suited
for low-power applications such as earbuds case charging. A
unique Ping detect feature gives the user an early indication of the
wireless charger connection and improves thermal performance at
the end of complete battery charging. Low under-voltage lockout
(UVLO) threshold allows the receiver to start up even with a weaker
digital ping strength signal from a transmitter over an extended
area.  …
