MAX17614 Evaluation Kit
General Description
The MAX17614 evaluation kit (EV kit) is a fully
assembled and tested circuit board that demonstrates
the MAX17614 ideal diode/power source selector in a
20-pin TQFN-EP package. The EV kit allows two power
sources to be connected as inputs. The load gets power
from the higher voltage power source for ideal diode
applications. For power source selector applications, the
load gets power from either of the two power sources by
driving respective EN pins. The EV kit configurations
allow independent settings for the two instances to
demonstrate adjustable overvoltage, undervoltage,
reverse current blocking, three current-limit types
(autoretry, continuous, and latch-off) with different
programmable current-limit thresholds (from 0.15A to
3A). For more details about the IC benefits and features,
refer to the MAX17614 IC data sheet.

  • Page 4 Power Source Selector The EN pin of the MAX17614 allows a system microcontroller to turn ON/OFF power to the load, thus enabling the system to select a power source based on operating conditions. Configure shunt position not installed for jumpers JU104 and JU204 and drive the EN pins of devices U1 and U2 high or low for selection of input supply voltages.
