1 / 35 page  Dual-Mode Wireless Power Receiver for 5W Applications P9225-R Datasheet © 2018 Integrated Device Technology, Inc. 1 November 12, 2018 COM1 VRECT SINK OUT VDD5V EOC SCL INT SDA EN On AC1 AC2 VOSET ILIM RPPO RPPG TS BST2 COM2 COMB VDD18 GND LED VDD18V Off BST1 COMA P9225-R LS COUT CS Description The P9225-R is a high-efficiency wireless power receiver (Rx) capable of operating in both WPC and PMA protocols. Using magnetic inductive charging technology, the receiver converts an AC power signal from a resonant tank into a regulated DC output voltage ranging from 4.5V to 5.5V. The integrated, low RDSON synchronous rectifier and ultra-low dropout linear (LDO) regulator offers high efficiency making the product ideally suited for battery- operated applications. The P9225-R includes an industry-leading 32-bit ARM® Cortex®-M0 microprocessor offering a high level of program- mability. The P9225-R also features a programmable current limit and a patented over-voltage protection function eliminating the need for additional capacitors generally used by the receivers minimizing the external component count and cost. Together with the P9038-R transmitter (TX), the P9225-R is a complete wireless power system solution for power applications up to 5W. The P9225-R is available in a 52-WLCSP package, and it is rated for 0°C to 85°C ambient operating temperature range. Typical Applications Headsets, tablets Digital cameras Portable media player Accessories Medical Features Single-chip solution supporting up to 5W applications WPC-1.2.4 compliant, PMA SR1 compatible Patented over-voltage protection clamp eliminating external capacitors 82% peak DC-to-DC efficiency with P9038-R TX Fully integrated synchronous rectifier with low RDS(ON) switches Programmable output voltage: 4.5V to 5.5V Embedded 32-bit ARM® Cortex®-M0 processor Dedicated remote temperature sensing Programmable current limit Active-low enable pin for electrical on/off Active-high End-of-Charge input pin Open-drain interrupt flag Support for I2C interface 0°C to +85°C ambient operating temperature range 52-WLCSP (2.64 × 3.94 mm; 0.4mm pitch) Typical Application Circuit |
