General Description
Benefits and Features
●ꢀ 4.5Vꢀtoꢀ36VꢀOperatingꢀVoltageꢀRange
The MAX14588 evaluation kit (EV kit) is a fully assembled
and tested circuit board that demonstrates the MAX14588
adjustable overcurrent and overvoltage protector. The
EV kit features TVS diode on input and Schottky diode
on output. Input power to the EV kit uses a 4.5V to 36V
input supply.
●ꢀ FeaturesꢀTVSꢀDiodeꢀandꢀSchottkyꢀDiode
●ꢀ EvaluatesꢀThreeꢀCurrent-LimitꢀTypes,ꢀ
Current-LimitꢀThreshold,ꢀOVLO,ꢀandꢀUVLO
●ꢀ ProvenꢀPCBꢀLayout
●ꢀ FullyꢀAssembledꢀandꢀTested
The EV kit circuit can be configured to demonstrate the
device’s different current-limit types, adjustable overvolt-
age, undervoltage, and current-limit threshold.

Procedure
TheꢀEVꢀkitꢀisꢀfullyꢀassembledꢀandꢀtested.ꢀFollowꢀtheꢀstepsꢀ
below to verify board operation:
1) Verify that all jumpers are in their default positions.
2)ꢀ ConnectꢀtheꢀUSBꢀcableꢀtoꢀJ1ꢀfromꢀaꢀcomputerꢀorꢀ
connectꢀaꢀ5VꢀDCꢀpowerꢀsupplyꢀtoꢀTP3.
Current-Limit Threshold
TheꢀEVꢀkitꢀfeaturesꢀaꢀjumperꢀ(JU1)ꢀtoꢀselectꢀcurrent-limitꢀ
threshold.ꢀInstallꢀaꢀjumperꢀasꢀshownꢀinꢀTableꢀ2ꢀtoꢀchangeꢀ
the current-limit threshold.
3)ꢀ VerifyꢀthatꢀLED1ꢀisꢀon.
4)ꢀ Connectꢀaꢀ20VꢀDCꢀpowerꢀsupplyꢀtoꢀIN.ꢀVerifyꢀthatꢀ
OUTꢀisꢀ20V.
Useꢀtheꢀfollowingꢀequationꢀtoꢀcalculateꢀtheꢀcurrentꢀlimit:

5)ꢀ IncreaseꢀvoltageꢀonꢀtheꢀDCꢀpowerꢀsupplyꢀandꢀverifyꢀ
thatꢀtheꢀOUTꢀvoltageꢀgoesꢀdownꢀandꢀLED2ꢀisꢀonꢀ
whenꢀinputꢀreachesꢀapproximatelyꢀ33V.
