General Description
The G5178A G5178B and G5178C 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 G5178B and G5178C a 120Ω on-chip load
resistor is added for output quick discharge when the
switch is turned off.
G5178A G5178B and G5178C 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.
Applications
