Power Supply

Connect a DC power supply, with 500mA output current capability, across the two pins built

with connector J2. Make sure the polarity is properly respected: reverse polarity will destroy the

NCP5612. Set up the power supply to 3.6V. Although the supply voltage can be adjusted

between 2.85V – 5.5V for engineering purpose, the associated MCU test board is limited to

3.6V: double check the power supply before to turn ON the supply.

Test Procedure:

Digital Control:

It is possible to drive the NCP5612 by means of an external controller, leaving aside the MCU

test package. In this case, connect an external pulse generator to connector J1 /IDC10. The

external controller shall send the data according to the SWIRE protocol depicted into the

NCP5612 data sheet. The chip is capable to support a 100kHz transfer rate.

System Operation:

Note: the MCU board is reserved for manufacturing only and is NOT provided with the

NCP5612 demo board

Connect the IDC10/J1 connector to the external MCU board with the ribbon cable.

Double check the power supply is set up at 3.6V, maximum rating is 3.8V. The MCU

board is powered by the same external DC supply once the ribbon cable is attached on

both boards.

Turn ON the power supply: LED D1 on the MCU board shall turns ON. Reset the MCU

if necessary by pushing the RESET button S7.

Push control button F3: the two LED shall be activated.

Push control button F7: the two LED shall be dimmed until OFF.

Since bounces are generated by the manual push buttons, non-linear operation can

happen during the test. This is normal and the part should NOT be rejected for such a

reason.

Double check the power supply is set up between 3.0V to 5.5V; make sure the external

MCU can support the same power supply range.

Send the appropriate data frame to control the two LED.

Turn ON the power supply .
