Description
The PI3PD22919 is a small, ultra-low rON load switch with con-
trolled turn on. The device contains a N-channel MOSFET that
can operate over an input voltage range of 0.75 V to 3.6 V and
switch currents up to 4-A. An integrated charge pump biases the
NMOS switch in order to achieve a minimum switch ON resis-
tance (rON). The switch is controlled by an on/off input (ON), via
an active low enable pin.
The PI3PD22919 has a 1250Ω on-chip load resistor for quick out-
put discharge when the switch is turned off.
The PI3D22919 has an internally controlled rise time in order
to reduce inrush current. The PI3D22919 features a rise time of
880μS at 3.6V.
The PI3D22919 is available in an ultra-small, space-saving 8-pin
CSP package and is characterized for operation over the free-air
temperature range of –40°C to 85°C.
