MAX14588EVKIT Datasheet, PDF (3/8 Pages) Maxim Integrated Products – 4.5V to 36V Operating Voltage Range

MAX14588 Evaluation Kit
Evaluates: MAX14588
Quick Start
Required Equipment
● MAX14588 EV kit
● 36V DC power supply
● Multimeter
● USB-A male to USB-B male cable or
5V DC power supply
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Verify that all jumpers are in their default positions.
2) Connect the USB cable to J1 from a computer or
connect a 5V DC power supply to TP3.
3) Verify that LED1 is on.
4) Connect a 20V DC power supply to IN. Verify that
OUT is 20V.
5) Increase voltage on the DC power supply and verify
that the OUT voltage goes down and LED2 is on
when input reaches approximately 33V.
6) Decrease voltage on the DC power supply and verify
that OUT goes back and LED2 is off when the input
reaches approximately 32V.
Detailed Description of Hardware
The MAX14588 EV kit is a fully assembled and tested
circuit board that demonstrates the MAX14588 1A adjust-
able overcurrent and overvoltage protector IC in a 16-pin
surface-mount TQFN-EP package.
Using jumper JU1, the EV kit circuit can be configured to
evaluate different current-limit thresholds with a different
resistor on SETI. Using jumpers JU3–JU5, the EV kit circuit
can be configured to evaluate the internal OVLO/UVLO
threshold or external threshold using a resistor-divider.
Using jumpers JU14 and JU15, the EV kit circuit can be
configured to evaluate different current-limit types (autore-
try, latchoff, and continuous). The EV kit also features
LEDs to indicate the power for logic pins and FLAG status.
Current-Limit Threshold
The EV kit features a jumper (JU1) to select current-limit
threshold. Install a jumper as shown in Table 2 to change
the current-limit threshold.
Use the following equation to calculate the current limit:
R _SETI
( kΩ )
= ⁶¹⁰⁰
I_LIM (mA)
UVLO/OVLO Threshold
Use jumpers JU3–JU5 to select UVLO and OVLO thresh-
old. See Table 3 for jumper settings.
