DESCRIPTION

JW7110 is a low on-resistance dual channel load

switch with programmable turn-on rise time. It

contains two n-channel MOSFETS that can

provide 6A maximum continuous current per

channel. Each channel can operate over an input

voltage range of 0.8V to 5.5V.

Each channel can be independently controlled by

a low-voltage control signal through EN1/EN2 pin.

In JW7110, a 200Ω load resistor is integrated for

quick output discharge when load switch is turned

off. The optional external capacitor connected to

SS1/SS2 is used for output slew rate control.

QUICK START GUIDE

1. Connect the positive terminal and negative terminal of the load to VOUT1/VOUT2

and GND of EVB, respectively.

2. Connect a power supply between VBIAS and GND with the supply in “OFF” state.

Set the output voltage of the power supply to 2.5V-5.5V.

3. Connect a power supply between VIN1/VIN2 and GND with the supply in “OFF”

state. Set the output voltage of the power supply to 0.8V~VBIAS.

4. Connect a power supply between EN1/EN2 with the supply in “OFF” state. Set the

output voltage of the power supply to 1V-5.5V.

5. Turn on the power supply and the evaluation board starts operating in normal

condition.
