Ultra Small, Low Input Voltage, Low RON Load Switch CXAS42223 is an ultra small, low RON load switch with controlled turn on. The device contains an N-Channel MOSFET that operates over an input volt

   产品概述 返回TOPozF嘉泰姆

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.ozF嘉泰姆

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.ozF嘉泰姆

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