DIO7297

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

Features

Descriptions

DIO7297 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. DIO7297 is housed in

WLCSP-4 with 0.5mm pitch. It operates over the

free-air temperature range of -40°C to 85°C.



Low-Input Voltage: 1.2V to 5.5V



Ultra-Low ON-State Resistance

r_ON=47mΩ at V_IN=5.0V

r_ON=50mΩ at V_IN=4.2V

r_ON=54mΩ at V_IN=3.6V

r_ON=67mΩ at V_IN=2.5V

r_ON=88mΩ at V_IN=1.8V

r_ON=177mΩ at V_IN=1.2V



Continuous Switch Current: 500mA (Max.)

Ultra-Low Quiescent Current: 67nA at 1.8V
