2.3 LED Indicators

Figure 2-7 shows the physical location of each LED indicator on the EVM. Placement is the same for all EVMs in the family.

DRV8243S-Q1EVM, DRV8243H-Q1EVM, DRV8244S-Q1EVM, DRV8244H-Q1EVM, DRV8245S-Q1EVM EVM LED IndicatorsFigure 2-7 EVM LED Indicators

Refer to Table 2-3 for descriptions of each LED on the EVM.

DesignatorLabelDescription
D1Status

Indicates MCU execution and DRV status.

Flashing approximately 0.1Hz: DRV in sleep mode

Flashing approximately 1Hz: DRV ready, outputs disabled

Continuously on: DRV output enabled/ active

Alternating with nFAULT: MCU abort exception

This LED flashes continuously until the VM power supply is turned on.

D2nFAULTIndicates fault condition. Normally off. To briefly see this LED flash when the MCU becomes active or RESET is pressed is normal.
D3VMVM supply indicator. Normally if supply is connected to +BAT input.
D5MODEEZFET_LITE mode indicator. Normally on during GUI control. On/ flashing when using the JTAG interface.
D6PWREZFET_LITE power indicator (must be active for GUI control).
D73V33.3V for MCU (must be active for GUI control).
