DIO7290

Ultra-Small, Low-Input Voltage, Low r_ONLoad Switch

Features

Descriptions



Low-Input Voltage: 1.2V to 5.5V

DIO7290 device is low R_ONMOSEFT controlled by

external logic pin, allowing optimization of battery

life, and portable device autonomy. It includes a

P-channel MOSFET that operates over an input

voltage range of 1.2V to 5.5V. An on/off input (ON)

controls the switch that can interface with low

voltage control signals. A 120Ω on chip load

resistor is added for output quick discharge when

the switch is turned off. DIO7290 is packaged in

WLCSP-4 with 0.4mm pitch. It is characterized for

operation over the free-air temperature range of

-40°C to 85°C.



Ultra-Low ON-State Resistance

r_ON=48mΩ at V_IN=5.0V

r_ON=50mΩ at V_IN=4.2V

r_ON=55mΩ at V_IN=3.6V

r_ON=65mΩ at V_IN=2.5V

r_ON=85mΩ at V_IN=1.8V

r_ON=175mΩ at V_IN=1.2V



DC Current Up to 2A

Ultra-Low Quiescent Current: 67nA at 1.8V

Ultra-Low Shutdown Current: 33nA at 1.8V

Low Control Input Thresholds Enable Use of

1.2V/1.8V/3.6V/4.2V/5.0V Logic



Controlled Slew Rate to Avoid Inrush Current

Package: WLCSP-4 (0.4mm Pitch)

Applications

Cellular Phones

GPS Devices

Digital Cameras

Peripheral Ports

Portable Instrumentation

RF Modules

Personal Digital Assistants (PDAs)

MP3 Players
