MAX20333 Evaluation Kit
General Description
Quick Start
The MAX20333 evaluation kit (EV kit) is a fully assembled
and tested circuit board that demonstrates the MAX20333
0.2A to 4.75A adjustable current-limit switch device. The
EV kit comes with the MAX20333ENL+ installed. The EV
kit board can also be used to evaluate MAX20333A/B/C/D/
E/F/G/H/I/J/K/L/M/N.
Required Equipment
● MAX20333 EV kit
● 9V Power Supply
● 5V Power Supply
● Multimeter
● Load Box
Features
● 3.5V to 22V Operating Voltage Range
Procedure
(3.3V to 22V for MAX20333L/M/N)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
● Output and Flag LED Reading
● Adjustable Current Limit Setting
● Adjustable Blanking Time (PBT version)
● Proven PCB Layout
1) Connect 5V on V TP14.
IO
2) Connect 9V on INPUT TP5. Use the voltmeter to
check that the OUT TP6 voltage is 9V.
3) Connect the load box to OUT. Increase the load
current and verify that the OUT voltage goes down
when output current goes up to about 1A, and D3
turns on (when overcurrent is in normal mode, FLAG
is asserted).
● Fully Assembled and Tested
EV Kit Contents
● EV Kit Board Containing a MAX20333ENL+
4) Remove the output load. Cycle the INPUT power,
verify D3 is off, and OUT voltage is 9V.
Ordering Information appears at end of data sheet.
5) Change JU3 to the 1–2 position. Connect the load
box to OUT.
6) Increase the load current and verify the OUT voltage
goes down when output current goes up to about 2A,
and D3 turns on (when overcurrent is in high current
mode, FLAG is asserted).

Enable Pin and Mode Selection
Detailed Description
Use jumper JU2 and JU3 to enable the device and select
the mode.
The MAX20333 EV kit is a fully assembled and tested
circuit board demonstrating the MAX20333 0.2A to 4.75A
adjustable current limit switch device in a 15-bump WLP
package.
NVP or PBT Version
Use jumper JU4 to connect NVP to the gate of external
pFET or connect PBT to a capacitor for adjustable blank-
ing time.
LED Indicator
The EV kit features D2 to indicate power on output and
D3 to indicate FLAG is asserted.

Current Limit Threshold
MAX20333/A/B/C/D/E
The current limit is set with the SETI resistor. Use JU1 to
select the desirable current limit in normal mode (NM) or
high current mode (HCM).
