CXES4273高级负载管理交换机针对需要高度集成的解决方案的应用程序真正的反向电流阻断TRCB功能在接通和断开状态下阻止从VOUT到车辆识别号的不需要的反向电流3.5A最大持续电流能力

CXES4273高级负载管理交换机针对需要高度集成的解决方案的应用程序。它通过严格的关断状态电流目标和高负载电容（高达100mF）断开直流电源轨（<6V）供电的负载。CXES4273由旋转率控制的低阻抗MOSFET开关（典型为23mW）和集成模拟特性组成。回转率控制的导通特性可防止浪涌电流和由此导致的电源轨上的过大电压降。CXES4273具有真正的反向电流阻断（TRCB）功能，在接通和断开状态下阻止从VOUT到车辆识别号的不需要的反向电流。极低的关断状态电流消耗（最大小于1毫安）有助于满足备用电源要求。输入电压范围从1.5V到5.5V直流，支持广泛的应用于消费、光学、医疗、存储、便携式和工业设备电源管理。开关控制由一个逻辑输入（有源高电平）管理，该逻辑输入（有源高电平）能够直接与低压控制信号/通用输入/输出（GPIO）接口，而无需外部下拉电阻器。该设备采用先进、完全“绿色”兼容、1.2毫米x 0.8毫米、晶圆级芯片级封装（WLCSP），背面层压

The CXES4273 advanced load management switch targets applications requiring a highly integrated solution. It disconnects loads powered from the DC power rail (<6V) with stringent off-state current targets and high load capacitances (up to 100mF). The CXES4273 consists of slewrate controlled low-impedance MOSFET switch (23mW typical) and integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. The CXES4273 has a True Reverse Current Blocking (TRCB) function that obstructs unwanted reverse current from VOUT to VIN during both ON and OFF states. The exceptionally low off-state current drain (<1mA maximum) facilitates compliance with standby power requirements. The input voltage range operates from 1.5V to 5.5VDC to support a wide range of applications in consumer, optical, medical, storage, portable, and industrial device power management. Switch control is managed by a logic input (active HIGH) capable of interfacing directly with low-voltage control signal / GeneralPurpose Input / Output (GPIO) without an external pulldown resistor. The device is packaged in advanced, fully “green” compliant, 1.2mm x 0.8mm, Wafer-Level Chip-Scale Package (WLCSP) with backside lamination
