PI3PD22919
Ultra Small, Low-Input Voltage, Low RON Load Switch
Features
Description
ÎÎIntegrated Load Switch
The PI3PD22919 is a small, ultra-low rON load switch with controlled 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
ÎÎInput Voltage: 0.75-V to 3.6-V
ÎÎUltra-Low ON Resistance:
− Max RON over temperature = 9.8mΩ at VIN = 3.6V
NMOS switch in order to achieve a minimum switch ON resistance (rON). The switch is controlled by an on/off input (ON), via
an active low enable pin.
ÎÎUltra Small CSP-8 package
−0.95 mm x 1.95 mm, 0.5-mm Pitch
The PI3PD22919 has a 1250Ω on-chip load resistor for quick output discharge when the switch is turned off.
ÎÎ4-A Maximum Continuous Switch Current
ÎÎShutdown Current 5.5-μA max
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.
ÎÎLow Threshold Control Input
ÎÎControlled Slew Rate to Avoid Inrush Currents
ÎÎQuick Output Discharge Transistor
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.
ÎÎESD Performance Tested Per JESD 22
− 4000-V Human-Body Model (A114-B, Class II)
