4.4 DRV8329AEVM Configurability

The DRV8329AEVM includes a variety of user-selectable jumpers and unpopulated components on the PCB to choose user settings and evaluate the DRV8329A, DRV8329B, DRV8329C, or DRV8329D device. A summary of those selectable settings is listed in Table 4-2 (defaults in bold) and can be seen on the board in Figure 4-6.

Id.Setting NameDescriptionPositionFunction
AnSLEEP switchPlaces DRV8329 in sleep modeS2 = LeftSleep mode
S2 = RightOperating mode
BDead time potentiometer, jumper, & resistorJumper to enable dead time control from potentiometer and potentiometer used to set the resistance for DT pin.J1 = PopulatedDT from pot is enabled
J1 = DNPDT from pot is disabled
R1 (CW = more DT, CCW = less DT)Sets dead time of gate driver outputs
R2Fixed resistor for DT pin
CCSA input filterInput filter to filter any Vsense switching transients at the current sense amplifier inputs.R45 = R43 = 0 ohm C30, C31, C32 = DNPCSA input filtering
