LPSemi/微源半导体 LP4080H DFN-8 TWS耳机的超高效线性充电器
General Description
The LP4080H is an ultra-low power linear charger targetingat TWS earphone applications. It contains a linear chargerto charge the Li-ion battery in the earphone with a CHGbcharging status indication and an ENb input to disable thecharger when needed. The constant charge current (CC)of the charger is programmable via the ISET pin by anexternal resistor. The charger has an ideal-diode mode forhigh efficiency and low heat operation. Two logic signalsare offered to work with the Bluetooth SoC. The RESEToutputs a reset signal to the SoC every time the earphoneis placed into the charging case. The PWRON outputs apulse signal to turn on the earphone SoC every time theearphone leaves the charging case. The GPO pin is amultifunctional output pin for system design. All thesesignals can also be controlled via a one-wirecommunication.The whole system is in a small 8-pin 2x2 DFN package.
Applications
◆ TWS earphones
◆ Wireless microphone
◆ Smart Glasses
