boards for the three typical applications in photograph and
schematic form.
There are also 2 mini development boards named
ISL6146DEVAL1 and ISL6146EEVAL1. These boards are
provided as a matching pair of either the ISL6146D or ISL6146E
part type directly from the website or with either the ISL6146A or
ISL6146B installed from the factory (contact support if desired).
The small size (1” x 0.5”) is suitable for adding into an existing
circuit using another OR-ing FET controller. These small and
simple boards have only the necessary components for its
implementation utilizing the already present MOSFET(s) in the
circuit it is being added to.
The mini evaluation circuit is designed to give the user the
flexibility in either defaulting or signaling the enable ON or to use

ISL6146 Evaluation Platforms
Description and Use of the Evaluation Boards
The three ISL6146 evaluation boards are used to demonstrate
the four application configurations discussed earlier. All the
boards have ADJ shorted to VOUT with the PCB layout having the
component footprints to insert a resistor of choice between ADJ
and GND to adjust the HS COMP Vth. Likewise, the VIN is
connected to BIAS but these can be separated to provide an
adequate BIAS voltage when OR-ing <3V supplies or if providing
a separate from VIN voltage to BIAS.
The ISL6146AEVAL1Z is configured to have a 8.5V minimum
turn-on threshold with a 1.2V hysteresis.
The ISL6146BEVAL1Z is configured as a minimally featured
maximum performance OR-ing FET controller for 3V to 20V.
The ISL6146CEVAL1Z is configured to operate with a 10.8V lower
turn on threshold and 14.9V upper turn-off threshold.
All three boards are equipped with 50A capable FETs for high
current evaluations and with a minimum of V IN and V OUT bulk
capacitance likely to be found in any power system design.
After determining the BIAS source along with V IN voltage criteria
and configuring the evaluation board if necessary, for the
application to be evaluated the board is ready for power.
Apply the BIAS voltage first (via the test points labeled BIAS), if
separate from VIN, then the V IN voltage. Monitor the provided
test points for device performance with current loads up to 50A.

a VIN voltage threshold to turn-on the IC function.
Provided are access to the IC VIN, GATE and VOUT pins for best
practices connections to the MOSFET(s) along with adjustable HS
Vth via the ADJ pin and the FAULT output.
The mini evaluation circuit is documented in Figures 62 & 63 and
Table 2.
