SSP707X

Overview

SSP707X is a power management chip (PMIC) designed by SinhMicro for applications such as smart charge compartments of Bluetooth headsets, and smart watches. The chip integrates an overvoltage protection circuit, and the input withstand voltage is as high as 38V; The chip has a built-in high-efficiency switching charge module (Charger) and a boost module with adjustable output voltage to meet the needs of fast charge and earphones synchronous charge in the smart charge compartment; On-chip integrated Power Line Carrier (PLC) control module for data communication on the power path; The chip can be used alone or with MCU through the IIC interface; In response to the solution requirements of TWS, the chip has built-in headphone plug-in or pull-out detection wake-up circuit and UART Communication Level Shift module, which greatly simplifies the peripheral materials of the solution.
