LT3652EMSE#PBF, Battery Charger, Lead Acid/LiFePO4/ Li-Ion/Li-Pol, 14.4 V/2 A Charge, -40 to 125 Deg C, MSOP-EP-12 /Код si-672949

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Управление Питанием Батарей\Микросхемы Зарядных УстройствLT3652 is a complete monolithic step-down battery charger for solar power. This provides a constant-current/constant-voltage charge characteristic, with maximum charge current externally programmable up to 2A. The charger employs a 3.3V float voltage feedback reference, so any desired battery float voltage up to 14.4V can be programmed with a resistor divider. This employs an input voltage regulation loop, which reduces charge current if the input voltage falls below a programmed level, set with a resistor divider. When this is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power. It can be configured to terminate charging when charge current falls below 1/10 of the programmed maximum (C/10). Typical applications are solar powered applications, remote monitoring stations, LiFePO4 (lithium phosphate) applications, portable handheld instruments, 12V to 24V automotive systems. • Input supply voltage regulation loop for peak power tracking in (MPPT) solar applications• Wide input voltage range from 4.95V to 32V (40V Abs maximum)• Programmable charge rate up to 2A• User selectable termination is C/10 or on-board termination timer• No VIN blocking diode required for battery voltages <= 4.2V• 1MHz fixed frequency, 0.5% float voltage reference accuracy• 5% charge current accuracy, 2.5% C/10 detection accuracy• Binary-coded open-collector status pins• 12-lead plastic MSOP package• Temperature range from -40°C to 125°C
