LS2364

1 Ch NiMH Battery Charger Controller LS2364 Features High accuracy in voltage detecting resolution: ~1mV/step for adjusting battery charge full condition as –deltaV, or 0deltaV (& over 16.4min.). (meet industrial specification about battery charge full request, -delta V = 5~10 mV ) Build-in special noise cancellation circuit for filtering noise from circuit Multiple charge process for different battery voltage condition: Battery Alive, Pre-Charge, Fast Charge and Trickle Charge. Constant Current charge method in each charge process. Providing multiple protection: Pre-Charge Time Out protection, Fast Charge Time Out protection, Maximum Battery Voltage protection. Single pin for economic RC oscillator circuit. Dual color LED status display: Power On/ battery defect/ Charging/ full. Working Voltage: 3.3 Volt. Package: Package: SOP-8.
