AAT4282A EVAL:

Dual Slew Rate Controlled Load Switch

Setup and Test

Test: RDS(ON) over VIN using Keithley V/I source 2430

1. Configure the specified test equipment as shown in Figure 2

2. Connect a floating Kelvin pulse from Keithley V/I source between INA and OUTA (with VIN as positive side,)

set the voltage pulse to 1V with 5ms pulse width, the compliance set to 100mA (the two sensing output

wires need to connect as close as possible to the INA and OUTA pins.)

3. Remove JP1 jumper to disconnect INA and INB; enable ENA and FAST; disable ENB by setting JP3 to

GND.

4. Turn on the input power supply and set to desired input voltage based on the DC voltmeter.

5. Power up the Keithley V/I source and read the voltage (VDS) and the current (IDS) measurements on the

Keithley V/I source.

RDS(ON) =

VDS

IDS

Vary the input voltage from 1.8V to 6.5V to observe RDS(ON) at different input voltages.

7. Repeat steps 1 though 6 with different compliance current from 100mA to 2A.
