The LTC®4070 allows simple charging of Li-Ion/Polymer batteries from very low current, intermittent or continuous charging sources. The 450nA to 50mA operating current makes charging possible from previously unusable sources. With the addition of an external pass device, shunt current may be boosted to 500mA. Stacked cell high voltage battery packs are inherently balanced with shunt charging.

The bq24210/2 series of devices are highly integrated Li-ion linear chargers devices targeted at space-limited portable applications. The high input voltage range with input overvoltage protection supports low-cost unregulated adapters. The input voltage regulation loop with programmable input voltage regulation threshold make it suitable for charging from alternative power sources, such as solar…

The bq25504 is the first of a new family of intelligent integrated energy harvesting Nano-Power management solutions that are well suited for meeting the special needs of ultra-low power applications. The product is specifically designed to efficiently acquire and manage the microwatts (µW) to miliwatts (mW) of power generated from a variety of DC sources like photovoltaic (solar) or thermal elec…

The Demo Board DC1830B-D is a battery charger controller with maximum power point control (MPPC) featuring the LTC4000-1. MPPC extracts near maximum power from high impedance sources such as solar panels, wind turbines or fuel cells. MPPC is achieved by means of an input voltage regulation control loop. This board should be connected to a front-end DC/DC power supply for a complete charger solution.

The solar-LED streetlight controller consists of one 80 W battery charger and one 25 W LED driver. During the daytime, when there is sufficient sunlight, the charger converts the electricity from the solar panel and charges the battery. At nighttime, the battery powers on the LED lamp as streetlight.

Demonstration circuit 1830B is a battery charger controller and PowerPath manager with maximum power point control (MPPC) featuring the LTC4000-1. MPPC extracts near maximum power from high impedance sources such as solar panels, wind turbines or fuel cells. MPPC is achieved by means of an input voltage regulation control loop. This board should be connected to a front-end DC/DC power supply for a complete charger solution.

The ADP5091/ADP5092 is a 2-channel ultralow power energy harvesting PMU in a compact 4 mm × 4 mm LFCSP package.

The STEVAL-ISV021V1 is a demonstration kit which consists of a complete energy harvesting module based on the SPV1050 ULP energy harvester and battery charger.

Demonstration Circuit 1568A is a 2A Monolithic Multi-Chemistry battery charger (Li-Ion/Polymer, LiFePO4, SLA, NiMH/NiCd) for solar power applications featuring the LT3652EDD. The LT3652 is a complete mid-power Li-Ion battery charger that can operate over a wide input voltage range.

The bq24650 is a highly integrated switch-mode battery charge controller. It provides input voltage regulation, which reduces charge current when input voltage falls below a programmed level. When the input is powered by a solar panel, the input regulation loop maintains the panel at maximum power output.
