3. Description

IP6816 is a multi-functional power management

SOC for total solution on TWS Bluetooth Earphone

Charging Box. It integrates with Qi wireless power

receiver, 5V-boost converter, lithium battery charging

management and battery level indicators.

IP6816 is highly integrated with abundant

functions, which makes the total solution size

minimized and BOM costed down.

The synchronous 5V-boost system of IP6816

provides rated 300mA output current with conversion

efficiency up to 93%. DC-DC converter operates at

1.5MHz, and can support low-cost inductors and

capacitors.

IP6816’s linear charging system supplies max

500mA charging current. With the change of IC

temperature and input voltage, IP6816 can

automatically adjust the charging current.

IP6816 can detects the TWS earphone

plug-in/plug-out in the Chargering Box independently.

While the earphone is put in the Chargering Box, it

enters the discharging mode automaticaly. When the

earphone is fully charged, the Chargering Box

automatically enters the sleep state, and the standby

current can be reduced to 30uA. The earphone’s

charge-end current can be Flexible and customizable,

such as 4mA or 8mA.

IP6816 can support 1/2/3/4 LED battery indicator,

The built-in 10bits ADC can accurately calculate the

Chargering Box’s battery capacity.

IP6816 is packaged with QFN16(4*4*0.75mm).
