Wireless Power Transmitter
for 15W Applications
P9242-R
Datasheet
Description
The P9242-R is a highly integrated, magnetic induction, wireless
power transmitter supporting up to 15W. The system-on-chip
operates with an input voltage range of 4.25V to 21V.
The transmitter includes an industry-leading 32-bit ARM® Cortex®-
M0 processor offering a high level of programmability while
consuming extremely low standby power. The P9242-R features
two LED outputs with pre-defined user-programmable blinking
patterns, buzzer, and programmable over-current protection
supporting a wide range of applications. The I2C serial
communication allows the user to read information such as voltage,
current, frequency, and fault conditions. The P9242-R includes an
under-voltage lockout and thermal management circuit to safe
guard the device under fault conditions. Together with the P9221-
R receiver (RX), the P9242-R is a complete wireless power system
solution.
The P9242-R is available in a lead-free, space-saving 48-VFQFN
package. The product is rated for a -40ºC to +85ºC operating
temperature range.
