FIGURE 3-1: THE BDC MOTOR CONTROL ADD-ON ARCHITECTURE
3.3.2 Attaching the Motor
The BDC add-on kit includes a 12V NMB PAN14EE12AA1 motor. This motor is
mounted on the board. The voltage is supplied to the motor through jumper J5. To use
an alternate motor, remove the shorting block from J5 and attach the two motor leads
to lines V and U. The V_MOT and GND connections are for a lab supply and are to be
used in lieu of the 2.5 mm power connector.
3.3.3 Power-Up
Voltage is supplied through the 2.5 mm jack connector J3, with a maximum rating of
+12VDC. The F1 LV Evaluation Platform must be configured to use expansion board
power by inserting the power jumper on J6. See “F1 LV Evaluation Platform for
Enhanced PIC
®
Microcontrollers User’s Guide” (DS41614) for more details.
3.3.4 Power Stage
The BDC add-on incorporates the classic full H-bridge drive made from two N-type and
two P-type MOSFETs. The maximum current rating is 8A on each MOSFET. Please
keep this in mind when designing your application or modifying the add-on hardware.
