Микросхемы и комплектующие LTC4065LXEDC-4.1#TRMPBF

Зарядное устройство , 1-элементная Li-Ion батарея, 5.5В вход, 4.2В/250мА зарядка, DFN-6

The LTC4065LXEDC-4.1#TRMPBF from Linear Technology is a standalone 250mA li-Ion battery charger in 6 pin plastic DFN package. It is a complete constant-current/constant voltage linear charger for single-cell lithium-ion batteries. The low external component count makes it well-suited for portable applications and designed to work within USB power specifications. The charge pin indicates when charge current has dropped to 10% of its programmed value. An internal timer terminates charging according to battery manufacturer specifications. When input supply is removed, it automatically enters a low current state, dropping battery drain current to <1µA. With power applied, LTC4065 can be put into shutdown mode reducing the supply current to <20µA. The full-featured LTC4065L also includes automatic recharge, low-battery charge conditioning (trickle charging) and soft-start (to limit inrush current).

• Charge current programmable up to 250mA with 5% accuracy
• VCC supply voltage range from 3.75V to 5.5V
• 4.1V pre-set float voltage with 0.6% accuracy for back-up
• high ambient temperature applications
• CC
• CV operation with thermal feedback to maximize charging rate without risk of overheating
• Charge current monitor output for gas gauging
• Automatic recharge
• Charges single cell li-ion batteries directly from USB port
• Reduced float voltage also minimizes swelling in prismatic and polymer cells

• Operating temperature range from -40°C to 85°C
