DESCRIPTION
The APE8937 is a small, ultra-low RON load switch
with controlled turn on. It contains one N-channel
MOSFET that can operate over an input voltage
range of 0.8V to 5.5V and support maximum
continuous current up to 6A. The switch is controlled
by an on/off input (EN), which is capable of
interfacing directly with low-voltage control signals.
Additional features include a 300Ω on-chip load
resistor for output quick discharge when switch is
turned off, in order to avoid inrush current, the rise
time is adjustable by an external ceramic capacitor
on the CT pin.
The APE8937 is available in an ultra-small, space
saving 2mmx2mm 8-pin DFN package with thermal
pad.
