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.

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

Table 2-3 EVM LED Indicators and their Functions
Designator Label Description
D1 Status

Indicates MCU execution and DRV status.

Flashing approximately 0.1 Hz: DRV in sleep mode

Flashing approximately 1 Hz: DRV ready, outputs disabled

Continuously on: DRV output enabled/ active

Alternating with nFAULT: MCU abort exception

This LED flashes continuously until VM power supply is turned on.
D2 nFAULT Indicates fault condition. Normally off. To briefly see this LED flash when the MCU becomes active or RESET is pressed is normal.
D3 VM VM supply indicator. Normally on if supply connected to +BAT input.
D5 MODE EZFET_LITE mode indicator. Normally on during GUI control. On/ flashing when using JTAG interface.
D6 PWR EZFET_LITE power indicator (must be active for GUI control).
D7 3V3 3.3 V for MCU (must be active for GUI control).
