3. Description

IP5516 is a multi-functional power management

SOC for total solution on TWS Bluetooth Earphone

Charging Box. It integrates with 5V boost converter,

lithium battery charging management and battery

level indicators.

IP5516 is highly integrated with abundant

functions, which makes the total solution with

minimized-size and low-cost BOM.

The synchronous 5V-boost system of IP5516

provides rated 300mA output current with conversion

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

1.5MHz frequency, can support low-cost inductors and

capacitors.

IP5516’s linear charger supplies max 500mA

charging current. With the change of IC temperature

and input voltage, IP5516 can automatically adjust the

charging current.

IP5516 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.

IP5516 can support 1/2/3/4 LED battery indicator,

The built-in 10bits ADC can accurately calculate the

Chargering Box’s battery capacity.

IP5516 is packaged with QFN16(4*4*0.75mm).
