ISL6144 Evaluation Board Overview
This section of the data sheet serves as an instruction
manual for the ISL6144EVAL1Z board. It also provides
design guidelines and recommendations for using the
ISL6144 for ORing MOSFET control. The ISL6144EVAL1Z
Control Board has two parallel feeds connected to each
other through N-channel ORing MOSFETs. Each ORing
MOSFET has an ISL6144 connected to it. This board
demonstrates the operation of Intersil’s ISL6144 HV ORing
MOSFET Controller IC in a typical 1 + 1 redundant power
system.
To demonstrate the functionality of the ISL6144, two power
supplies with identical output voltages are required as the
input to the ISL6144EVAL1Z board. This will show the ability
of the ISL6144 to provide the gate drive voltage for the
ORing N-Channel MOSFET. The ISL6144 also monitors the
drain (V OUT ), source (V IN ) and gate voltages in order to
provide reverse current protection and protection against
power feeds’ related faults.
Figure 15 shows a test setup used in the characterization of
ISL6144 in a 1 + 1 redundant power system.
ISL6144EVAL1Z Control Board (Rev C)
This board is configured with two input power feeds
connected in parallel for redundancy using ORing
MOSFETs. The ISL6144 allows the two rails to operate in
active ORing mode (This means that both feeds can share
15
the current if their respective voltages are close to each
other). ORing MOSFET’s gate drive voltage, control and
monitoring for each of these feeds are implemented using
the ISL6144.
The board has the following features:
? Evaluation of the ISL6144 in a 1 + 1 redundant power
system using a single board
? Has footprint for a total of three parallel MOSFETs per
feed. Number of MOSFETs used will depend on the load
current (on the standard ISL6144EVAL1Z board only one
MOSFET is populated per feed)
? Allows the user to test turn-on, slow turn-off, fast turn-off
and different fault scenarios
? Visual fault indication with Red LEDs
? Banana Connectors and test points for all inputs, outputs
and IC pins
? Can be easily connected to the power system prototype
for initial evaluation
Note that the board was designed to handle high load
currents (up to 20A per feed) with the appropriate MOSFET
selection.
