Brief Description

The KTE7001 is a single-chip 15-Watt wireless power

receiver that conforms to WPC/Qi standards v1.2.4 and

v1.3 Extended Power Profile (EPP) specifications. A

wireless power receiver provides regulated DC output

power derived from AC power that is magnetically

coupled into a connected wireless power receiver coil.

The KTE7001 integrates a full synchronous rectifier and

LDO to efficiently convert the wireless AC power into up

to 12V DC regulated power at up to 1.5A. The

embedded microcontroller with firmware and OTP

memory provides system monitoring, protection, and

communications back to the power transmitter.

The KTE7001 is packaged in an advanced, fully “green”

compliant, 2.66mm x 3.90mm, 52-bump Wafer-Level

Chip-Scale Package (6x9 WLCSP).

Applications

• Mobile Internet Devices, IoT, Accessories

• Battery Powered Medical, Industrial, Consumer

• Wireless Headsets, Headphones, Earbuds
