LP8501 Datasheet | Power

.Data Sheet.co.kr Advanced 1A Lithium-Ion Linear Battery Charger General Description The LP8501 is a single Lithium-Ion (Li-Ion) linear charge management controller for use in cost sensitive and portable applications. It bines high accuracy constant-current and constantvoltage regulation, cell preconditioning, tempera ture monitoring, automatic charge termination, charge-status indication, in a space-saving MSOP-8 package. The LP8501 applies a constant current up to 1A to the battery and the charge current can be programmed externally with a sense-resistor. The LP8501 automatically terminates the charge cycle when the charge current drops to the charge termination threshold (ITERM) after the charge-regulation voltage is reached. When the input supply is removed, the LP8501 automatically enters a low-power sleep mode, dropping the battery drain current to less than 1µA. A battery charge state output pin is provided to indicate Programmable Charge Current up to 1A 4.5V-7V Input Voltage Range Ideal for Single Cell (4.1V or 4.2V) Li-Ion or Li-Pol Batteries. Preset Charge Voltage with ±1% Accuracy Constant-Current/ Constant Voltage Operation Preconditioning of Low Voltage Cells Optional Cell-Temperature Monitoring Before and During Charge Charge Status Indication Automatic Battery Recharge Charge Termination by Minimum Current Automatic Low-Power Sleep Mode When Input Power is Removed Available in MSOP-8 Package Ro HS pliant and 100% Lead (Pb)-Free battery charge status through a display LED. Features Ideal for Single Cell (4.1V or 4.2V) Li-Ion or Li-Pol Batteries 4.5V-7V Input Voltage Range Programmable Charge Current up to 1A Precharge Constant-Current/Constant Voltage mode Automatic Low-Power Sleep Mode Automatic Battery Recharge Charge Termination by Minimum Current Optional Cell-Temperature Monitoring Before and During Charge Charge status through a display LED Automatic Low-Power Sleep Mode When Input Power is Removed Applications Portable Media...
