CXAS42259 CXAS42259C CXAS42259D是一系列高侧负载开关,设计用于从1.5V到5V的输入电压。负载开关通过元件是一个内部的25欧姆RON P沟道MOSFET,使器件能够支持高达3A的连续电流。此外,负荷开关支持1.5V。逻辑电平控制和关闭功能在一个小的1毫米X 1毫米4针WLCSP封装。CXAS42259C/D提供100μs的转换范围控制软启动。软启动功能可防止冲击电流事件拉低输入电源电压。CXAS42259C/D具有一个有源负载放电电路,当开关被禁用时,该电路在200Ω负载中切换,以自动放电电容性负载。启用输入上的活动下拉使CXAS42259C/D保持默认断开状态,直到启用引脚被拉到1.2V以上。内部电平移位电路允许低压逻辑信号切换更高的电源电压。启用电压可高达5.5V,不受输入电压的限制。带反向电压块功能的CXAS42259/D,如果车辆识别号消失或车辆识别号小于VOUT;设备将在无泄漏电流的情况下启动。CXAS42259/D工作电压范围使其成为锂离子和NMH/NiCad/碱性电池供电系统以及非电池供电应用的理想选择。该设备提供低静态电流和低关机电流,以最大限度地延长电池寿命。
