CXAS42223超小型低RON负载开关可控制开启含一个N沟道MOSFET在1V到5V的输入电压范围内工作开关由EN-pin控制直接与低压控制信号连接低控制输入阈值允许使用低压逻辑控制回转率以避免涌流

产品简介

The CXAS42223 is an ultra small, low R_ON load switch with controlled turn on. The device contains an N-Channel MOSFET that operates over an input voltage range of 1V to 5V. The switch is controlled by EN pin, which is capable of interfacing directly with low voltage control signals.

CXAS42223 device limits the output current to a safe level by using a constant current mode when the output load exceeds the current-limit threshold. An internal reverse voltage comparator disables the power switch when the output voltage is driven higher than the input to protect devices on the input side of the switch.Ao7嘉泰姆

The CXAS42223 is available in Green WLCSP-0.9×0.9-4B package and operates over a temperature range of -40℃ to +85℃.Ao7嘉泰姆
