LT1769規(guī)格書(shū)詳情
DESCRIPTION
The LT?1769 current mode PWM battery charger is a simple, efficient solution to fast charge modern rechargeable batteries including lithium-ion (Li-Ion), nickel-metalhydride (NiMH) and nickel-cadmium (NiCd) that require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 2A** DC current (3A peak current). Charge current can be programmed by resistors or a DAC to within 5. With 0.5 reference voltage accuracy, the LT1769 meets the critical constant-voltage charging requirement for Li-Ion cells.
FEATURES
■ Simple Solution to Charge NiCd, NiMH and Lithium Rechargeable Batteries—Charging Current Programmed by Resistors or DAC
■ Adapter Current Limit Allows Maximum Possible Charging Current During System Use*
■ Precision 0.5 Accuracy for Voltage Mode Charging
■ Available in 20-Lead Exposed Pad TSSOP and 28-Lead Narrow SSOP Packages
■ High Efficiency Current Mode PWM with 3A Internal Switch
■ 5 Charge Current Accuracy
■ Adjustable Undervoltage Lockout
■ Automatic Shutdown When AC Adapter is Removed
■ Low Reverse Battery Drain Current: 3μA
■ Current Sensing Can Be at Either Terminal of the Battery
■ Charging Current Soft Start
■ Shutdown Control
APPLICATIONS
■ Chargers for NiCd, NiMH, Lead-Acid, Lithium Rechargeable Batteries
■ Switching Regulators with Precision Current Limit
