High Performance Wireless Power Transmitter Controller

stage ICs, form simple, high-performance and

cost-effective wireless power transmitter

solutions suitable for a wide range of

applications.

1 Features

•

Input Voltage: 3.3V to 5.5V

Integrated ARM® Cortex® -M0

Compliant with WPC 1.2.4 EPP

Output to Control External DCDC Output

Reliable and Accurate Foreign Object

Detection (FOD)

NU1512 integrates all essential functions to

deliver regulated power and maintain robust

communications with WPC compliant

receivers. Used with NU1009A, the smallest

and most integrated power stage IC, the two-

chip turnkey design provides the most space

saving solutions.

•

LED for Charging Status and Fault

Reporting

•

PWM Output from 127.7KHz ± 6Hz

Built-in Frequency Shift Keying

Modulate (FSK)

NU1512 also emphasizes on providing

reliable and robust charging experience by

preventing any transient conditions, such as

receiver load variations and Rx/Tx coupling

changes, from disrupting communications

and continuous charging. The device adopts a

proven foreign object detection (FOD) scheme

to detect metal objects and prevent harmful

heating. The device also integrates the

protection features such as over-temperature

and over-current protections, input low-

voltage detection and input power limit.

•

Built-in Fast Charge Protocol

Input Low Voltage Detection

Limited Power to Prevent Overloading

Input Sources

•

Over-current Protection and Over-

temperature Protection with NTC Input

Internal Oscillator or External Crystal

Oscillator

Interface with NU1009A to Form High

Performance 15W Transmitter Solution

28 Pin 4mm  4mm QFN Package
