The power management products of Thinkplus Semiconductor used in Buds Z2 include SY8702, SY8801 and SY5500. SY8702 is a cost-effective port OVP device, using DC36V absolute maximum input voltage and as low as 28mΩ drain-source on-state resistance (Ron), with rapid overvoltage protection characteristics, is an ideal choice for consumer electronics port protection devices. SY8801 is a highly integrated power management SoC for TWS cradle, which integrates rich and efficient functions such as switch charging, load detection and intelligent communication for earbuds. Therefore, it is a classic product for cradle design and application favored by many brand customers. SY5500 is an intelligent PMIC designed by Thinkplus Semiconductor for the application of TWS earbuds. It can provide functions such as fast charging, intelligent communication and interaction, automatic resetting of crash, and power saving in hiber state for TWS earbuds. It is worth emphasizing that the IC size (1.6×1.6mm) developed by Thinkplus Semiconductor greatly saves the design space of power management for earbuds.

With its leading shipment volume and full range of commercial brands and models in the past two years, Thinkplus Semiconductor has become a leader of power management systems for integrated circuits in the TWS industry. Relying on more innovative technologies, better product performance and a richer product portfolio, Thinkplus Semiconductor will help customers create more flagship products in global markets.
