IDT debuts industry's smallest 2W wireless power receiver
Integrated Device Technology Inc. (IDT) has released what it boasts as the world's smallest 2W wireless power receiver and battery charger in a compact package geared for small form factors such as wearable applications. The IDTP9026 promises a high level of integration and lower external component count than competitive products, enabling designers to cut board area and BOM.
The device has a solution size requirement of less than 30 square millimetres, compared to 65 square millimetres for other available solutions. The chip is fully compliant with the Wireless Power Consortium's (WPC-1.1) standards.
Part of IDT's wireless power receiver product family, the IDTP9026 is a single-chip solution that uses patented technology to eliminate the need for many passive components traditionally required, helping OEMs cut costs while reducing overall application area without sacrificing performance, said the company.
The product's I2C interface allows programming of the charging current, charging voltage, termination current and the thermal control loop for maximum flexibility and control. Readings back from I2C include die and battery temperature, charging current and voltage, which can be used for custom control schemes or by the system's application and user interface.
To complete the system, IDT recommends the IDTP9038 the industry's first Qi-compliant single-chip wireless power transmitter supporting a 5V input. The two devices are fully compatible and are supported by IDT's design-in collateral and experience.
IDTP9026 samples are available for select customers.
