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.
