Linear LTMR8062 32V 2A电池充电解决方案

Linear公司的LTMR8062是完整的32V 2AμModuleR电池充电器,提供恒流/恒压充电特性,最大充电电流2A,输入电压从4.95V 到32V,最大到40V,主要应用在手持仪表,12V-24V汽车和台式计算器充电器以及太阳能电池充电.本文介绍了LTMR8062主要特性,方框图,以及多种应用电路, 32V 2A LTMR8062EV演示板电路图和材料清单(BOM).

The LTMR8062 is a complete 32VIN, 2A μModuleR power tracking battery charger. The LTM8062 provides a constant- current/constant-voltage charge characteristic, a 2A maximum charge current, and 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.

The LTM8062 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 the LTM8062 is powered by a solar panel, this input regulation loop is used to maintain the panel at peak output power.

The LTM8062 also features preconditioning trickle charge, bad battery detection, a choice of termination schemes and automatic restart.
