Triune Systems TS52001 Li-Ion Battery Chargers

Triune Systems TS52001 high efficiency Li-Ion battery chargers are DC/DC synchronous switching devices with Maximum Power Point Tracking (MPPT) for solar PV systems. The Triune Systems TS52001 features fully integrated power switches, internal compensation, and full fault protection. The TS52001 uses a temperature-independent photovoltaic MPPT calculator to optimize power output from the source during Full Charge Constant-Current (CC) mode. The switching frequency of 1MHz enables the use of small filter components, resulting in smaller board space and reduced BOM costs. These Li-Ion battery chargers feature a wide input voltage range of 4.0V to 7.2V and a junction operating temperature of -40ºC to 125ºC. The Triune Systems TS52001 is ideal for use in portable solar chargers, off-grid systems, wireless sensor networks, smoke detectors, and HVAC controls.
