The three ISL6146 evaluation boards are used to demonstrate four application configurations. 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 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 VIN and VOUT bulk capacitance likely to be found in any power system design.
After determining the BIAS source along with VIN 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 VIN voltage. Monitor the provided test points for device performance with current loads up to 50A.
