Jumper Configuration
Two jumpers are used on the DRV8313 EVM:
1. Three-Pin Jumper JP1: This jumper gives the user an option to select a 3.3-V source for on-board
MCU U5 (MSP430G2553). There are two sources of 3.3 V; one is a 3.3-V reference output of
DRV8313 and other is generated from input voltage VM through on-board LDOs U6 (LM2936) and U7
(TLV70433).
DRV8313 and other is generated from input voltage VM through on-board LDOs U6 (LM2936) and U7
(TLV70433).
(a) Position 1-2: In this position, MCU U5 is powered from DRV8313. This position is used for input DC
voltage range of 8 V to 48 V.
(b) Position 2-3: In this position, MCU U5 is powered from on board LDOs. This mode is used to avoid
over-heating of DRV8313 if input DC voltage VM is higher than 48 V.
2. Two-Pin Jumper JP2: This jumper must remain closed during all normal operating conditions of EVM
either through GUI or in stand-alone mode. The jumper is open only during the programming of
MSP430G2553 through 4-pin SPI-BY-WIRE method.

Power-Up Sequence
1. Make sure the jumpers are configured as explained in previous section.
2. Connect 3-phase BLDC motor terminal at terminal block J3. It is not important to observe polarity, as it
only applies to direction of rotation. Make sure all three pins are connected.
3. Apply VM (+24 V) at terminal block J2. EVM does not have reverse polarity protection, therefore make
sure positive terminal of power source is connected to VM and negative terminal is connected to GND.
4. Connect USB connector to the J6 USB connector from external PC/Laptop.
