[原创] ADI ADP5350高级电池管理PMIC解决方案

ADI公司的ADP5350是集成感性升压LED和三个LDO调节器的高级电池管理PMIC,一个用于单锂离子/锂离子聚合物电池充电的高性能降压调节器,一个燃油表,一个用于LED背光照明的高度可编程升压调节器,一个超低静态电流低压差(LDO)调节器和两个通用LDO调节器,主要用在可充电锂离子和锂离子聚合物电池供电设备,便携式消费电子设备,便携式医疗设备,便携式仪器仪表设备和可穿戴设备.本文介绍了ADP5350主要特性,功能框图,典型应用电路图以及评估板ADP5350CP-EVALZ主要特性,电路图,材料清单和PCB设计图.

The ADP5350, a power management IC (PMIC), combines onehigh performance buck regulator for single Li-Ion/Li-Ionpolymer battery charging, a fuel gauge, a highly programmableboost regulator for LED backlight illumination, and three 150 mALDO regulators.

The ADP5350 operates in trickle charge mode and in constantcurrent (CC) and constant voltage (CV) fast charge mode. Itfeatures an internal field effect transistor (FET) that permitsbattery isolation on the system power side.

The ADP5350 fuel gauge is a space-saving and low currentconsuming solution. It is optimal for rechargeable Li-Ion batterypowereddevices, and features a voltage-based, battery SOCmeasurement function.

The ADP5350 boost regulator operates at a 1.5 MHz switchingfrequency. It can be operated as a constant voltage regulator oras a supplemental constant current regulator for multiple LEDbacklight drivers.
