5V USB 输入两节锂电池高效充电芯片

ANT2801是一款宽范围电压输入，专门为双节锂电池充电的芯片,无需传统的9V专用适配器，只需标准5V适配器。可以通过外置电阻来设定芯片充电电流，通过外置电容来设定充电超时时间。低阻抗的电源通路可以使充电效率更高，减少充电时间，提高电池使用寿命。ANT2801可以自适应适配器的电流供应能力来自动调整充电电流，既能确保输入适配器不会出现过载现象，又能发挥适配器的最大电流能力，所以适用于各种直流设备以及标准USB充电设备。 • 充电电流可以达到1.2A\n• A包括涓流、恒流、恒压三种充电模式\n• 充电恒流值设定\n• 充电定时设定\n• 输入功率保护设定\n• 电池温度阈值设定\n• 内部集成高压低导通电阻功率管\n• 充电状态指示\n• 欠压锁定\n• 过压锁定\n• 过温保护;
