Evaluation Kit (EVKit) Operation

External Supply Setup

Set up a VCC power supply in the voltage range of 2.5V to 5.25V with the power supply output disabled.

For the 75

EVKit, connect the disabled Vcc supply connection to J6 pin 2 and GND to J6 pins 1 or 5.

For the 50

EVKit, connect the disabled Vcc supply connection to J6 pin 3 and GND to J6 pin 1, 2, 4, 6, 8, 9, or 10.

Logic Control Setup

With the logic control lines disabled set the HIGH and LOW logic levels to satisfy the levels stated in the electrical specifications table.

For the 75

EVKit, connect the disabled logic control lines to J6 EN (pin 3) and VCTL (pin 4).

For the 50

EVKit, connect the disabled logic control lines to J6 EN / LS (pin 5) and VCTL (pin 7).

See Table 9 for the logic truth table.

Turn On Procedure

Setup the supplies and EVKit as noted in the External Supply Setup and Logic Control Setup sections above.

Enable the VCC supply.

Enable the logic control signals.

Set the logic setting to achieve the desired Table 9 configuration. Note that external control logic should not be applied without VCC being

present.

Turn Off Procedure

Set the logic control pins to a logic LOW.

Disable the VCC supply.
