The ADP5350 operates in trickle charge mode and in constant current (CC) and constant voltage (CV) fast charge mode. It features an internal field effect transistor (FET) that permits battery isolation on the system power side. The ADP5350 fuel gauge is a space-saving and low current consuming solution. It is optimal for rechargeable Li-Ion battery- powered devices, and features a voltage-based, battery SOC measurement function. TYPICAL APPLICATION CIRCUIT Figure 1. The ADP5350 boost regulator operates at a 1.5 MHz switching frequency. It can be operated as a constant voltage regulator or as a supplemental constant current regulator for multiple LED backlight drivers. The ADP5350 LED drivers can support a wide range of LED backlight configurations, either multiple LEDs in parallel or in series. The ADP5350 low dropout (LDO) regulators are optimized to operate at low shutdown current and quiescent current to extend battery life. The device also operates as a load switch that can be fully turned off or on. The I2C-compatible interface enables the programmability of all parameters, including status bit readback for operation monitoring and safety control. The ADP5350 operates over the −40°C to +125°C junction temperature range and is available in a 32-lead, 5 mm × 5 mm LFCSP package and a 32-ball, 3 mm × 3 mm WLCSP package.
