2 Hardware Overview

The following sections explain the main components of the EVM (including connectors, configuration headers, and signal test points) in detail. Information such as voltage and current ratings is also present to state the limitations of the hardware to prevent potential damage to the board and its components. Figure 2-1 shows the main components of the DRV3901-Q1EVM. Table 2-1 gives a detailed description of each of the marked components. Both Figure 2-1 and Table 2-1 are referenced in the following sections.

ComponentDescription
A

J3: NAD_nFAULT resistor for Driver A

J8: NAD_nFAULT resistor for Driver B

BSTATUS LEDs. Refer to Table 2-4
C

J1: S1 button function selection header. Default position set to RST. PUSH function is not supported by firmware but firmware can be modified to perform any desired task when button is pressed and shunt is placed in PUSH position

S1: MCU Reset/Push function button. Only MCU Reset function is supported. Press the button to reset MCU when J1 is in RST position.

D

J7: Header for serial communication signals (RX, TX) and TDIO or TCK for programming main MCU (U5). Shunts are required for communication between main MCU (U5) and ezFET-LITE debugger.

J5: EZFET-LITE flashing connector. Header should be left disconnected. J6: USB connector

E

Main signal header. Refer to Table 2-3

F

U1: DRV3901-Q1 Driver A

P1: Driver A VREG and PVDD shunt jumper.

P3: Driver A VREG and VDRV shunt jumper.

GReverse battery protection, fuse, and EMI filter circuit

H

Main power supply (VBAT) connector

I

U8: DRV3901-Q1 Driver A

P2: Driver A VREG and PVDD shunt jumper.

P4: Driver A VREG and VDRV shunt jumper.
