LP7800S

High Efficiency TWS Case Manager

Features

General Description

 Maximum input voltage up to 30-V with 15-V

The LP7800S is an advanced TWS charging case

management IC targeting to improve the total battery run

time of the TWS earphones. The IC integrates a linear

charger which contains completely charge modes with

up to 350-mA charge current, and a smart discharge

management module to protect the battery from

over-discharged to maximize the battery run time. The

IC features a high efficiency synchronous boost module,

automatic load detection and Key control discharge,

automatic shut-down while the discharge current is

lower than the cut-off current threshold. The IC includes

charging and discharging status indication through two

LEDs controller. The quiescent current is less than

20-µA in standby mode.

input-over-voltage protection

 Charge management

- Maximum charge current up to 350-mA

- Default 4.2-V floating voltage with 1% accuracy

- Trickle current/constant current/constant voltage

mode supported

- Charge termination and automatic re-charge

- Dynamic power management for different input

source capacity application

 Discharge management

- Smart discharge voltage management to maximize

the battery life

- 96% peak boost efficiency

- Automatic load detection

- Key control

- Low cut-off discharge current

- Inductor current-limit protection

- Short circuit protection

The device provides various safety features for battery

charging and discharging, including device junction

temperature-limit protection for charging by limiting the

charge current, which is implemented by an internal

thermal foldback regulation loop, battery discharge

inductor current-limit protection, V_OUTshort protection

and thermal shutdown.

 Temperature Management

- Thermal foldback at 125℃ junction temperature

- Thermal shutdown at 150℃ junction temperature

 Built-in charging and discharging indication

 20-µA low quiescent current in standby mode

The LP7800S is available in a small 8-pin ESOP

package.
