TPL5010EVM Configuration
The evaluation board can work standalone or plugged into the MSP430F5529 LaunchPad.
2.3.1
Setting the Time Interval Period
Set the Time interval period by tuning the variable resistance (the trimmer can generate resistances in the
range between 1 k
Ω
and 200 k
Ω
).
To tune the value of the resistance:
1. Connect a DMM between pin 1 of R_SEL and GND.
2. Turn the screw on the top of the trimmer until you reach the desired value.
3. Disconnect the DMM at the end of the operation.
Alternatively, set the DRV pulse interval with the fix resistances (R_EXT1 = 500
Ω
, R_EXT2 = 0
Ω
). If
required, replace the resistances with customized ones.
See
for locations of the resistances REXT1 and REXT2.
