产品概述 返回TOPXIh嘉泰姆
The CXAS42258A CXAS42258B and CXAS42258C are .ultra-small, low
ON resistance (Ron) load switches with controlled turn
on. The devices contain a P-channel MOSFET that
operates over an input voltage range 1.2V to 3.6V. The
switch is controlled by an on/off input (EN), which is
capable of in interfacing directly with low-voltage control
signals. In CXAS42258B and CXAS42258C a 120Ω on-chip load
resistor is added for output quick discharge when the
switch is turned off.
CXAS42258A GCXAS42258 and GCXAS42258 are available in a
space-saving 4-terminal WLCSP with 0.4mm pitch. The
devices are characterized for operation over the free-air
temperature range for -40°C to 85°C.
