Like other wearables, TWS needs to be optimized for size and power. Halo’s new products are specifically designed to meet these demanding size and power requirements of TWS. HL6111R 5W Qi™ compatible wireless receiver solution is a compact solution designed for the charging cases. For the battery charging, Halo offers both an HL7046 linear charger and an HL7090 switching charger for the earbuds and for the charging cases. Depending on application needs, either solution can be adopted. In addition to these devices, Halo also provides a total reference design with board schematics and firmware to shorten the time to market, the company said in a press release.
“Halo is unique in offering these new products optimized for TWS applications,” said David Nam, CEO of Halo Micro. “With its low power consumption and highest efficiency wireless receiver and battery chargers, Halo is enabling the best user experience possible. With wealth of market proven IP’s and fast execution, Halo will continue to deliver application specific power management devices that perfectly fit customer’s needs.”
