Linear Technology LT1510/LT1510-5 Datasheet
The LT1510 is a current mode PWM battery charger designed to charge Nickel-Cadmium (NiCd), Nickel-Metal-Hydride (NiMH), and Lithium-Ion batteries. It features high efficiency with an internal 1.5A switch and requires only one external resistor to program the charging current.
The device operates at switching frequencies up to 500kHz, allowing for small inductor sizes. Key features include a precision 0.5% voltage reference, low reverse battery drain of 3uA, soft start capability, and shutdown control. It is available in various packages including SO, PDIP, and SSOP.
