Power-Source Selector for Dual-Battery Systems

General Description The MAX1538 selector provides power-source control for dual-battery systems. The device selects between an AC adapter and dual batteries based on the presence of the three power sources and the state of charge of each battery. Features ♦ Automatically Detects and Responds to

电源选择器，用于双电池系统

MAX1538选择器为双电池系统提供电源控制。器件可以根据三路电源连接与否以及每个电池的状态在交流适配器和两个电池之间进行选择。MAX1538包含模拟比较器，检测是否连接了交流/航空适配器、确定电池是否处于欠压状态。高速模拟电路允许器件在电源之间进行切换，采用先断后通时序，允许电池组热插拔。MAX1538可独立监视、选择电源，缓解了系统电源管理µP的工作，使其能够用于其他操作。该芯片简化了µP电源管理固件的开发，允许µP进入待机状态，从而降低系统功耗。\n\n MAX1538支持“重建模式”，该模式允许系统检测并充分利用电池容量。这种状态下，器件即使在连接交流适配器的情况下，也允许所 • 自动检测和响应：\n• 电池插入和移出\n• 是否连接航空适配器\n• 兼容于降压和升压充电器\n• 允许电源热插拔\n• 50µA最大电池静态电流\n• 允许使用航空设备电源\n• 简化电源管理µP固件的开发\n• 小尺寸28引脚薄型QFN封装(5mm x 5mm);
