低功耗、单/双电位电平监测器，带有滞回和集成微处理器复位电路

MAX6439-MAX6442是超低功耗电池监视器系列产品，集成了微处理器(µP)监控电路。这些电池监视器提供单路或双路低电池电压输出选择，用于指示电池正常(整个系统正常工作)、电池处于低电量状态(适合低功耗系统工作模式)或电池耗尽(禁止系统工作)。这些器件还含有一个独立的µP监控电路，用于监视VCC并产生一路低有效复位输出。利用手动复位功能可通过一个按钮复位µP，无需外部元件。\n MAX6439-MAX6442提供几种工厂预置的低电池电压门限组合，非常适合单节锂离子(Li+)电池或多节碱性电池/NiCd/NiMH电池供电系统。当电池电压降低至规定的低压门限时，低电池电压输出向系统发出报警信 \n• 工厂预置VBATT门限选择，可用于监视单节Li+电池或多节碱性电池/NiCd/NiMH电池 \n• 瞬时电池电压短路保护 \n• 低电流(3.6V时，典型电流2.5µA) \n• 单路或双路低电池电压输出选择 \n• 最小150ms /LBO延时周期 \n• 独立µP手动复位 \n• 工厂预置门限用于监视1.8V至3.3V的VCC \n• 150ms (最小)和1.2s (最小) VCC复位延时周期 \n• -40°C至+85°C工作温度范围 \n• 微型6引脚和8引脚SOT23封装 \n• 无需外部元件;
