2.5 Error Flag

The error flag pin (EF) indicates a number of different fault conditions as shown in Table 2-5. When an error is detected, EF pulls low.

Table 2-5 Error States Indicated by Error Flag

Error State

Description

Output short

Short-circuit current limit reached in voltage output mode.

Output open

Unable to reach correct output current in current output mode. Input voltage must be >350mV and supply voltage must be >10V to detect this fault condition.

SET pin short

SET pin current exceeding 1/10th of the output short circuit current limit.

Power supply undervoltage

Power supply voltage under 6V.

High die temperature

Die temperature exceeding 130°C.

The LED (D2) turns on when the XTR200 experiences one of the fault conditions listed in Table 2-5. Alternatively, users can monitor the EF by looking at the voltage at the EF test point.

The onboard LDO requires at least 7V to operate. Due to this limitation, the LED may not get the voltage required to work during a power supply undervoltage event. If the customer wants to use the LED to detect power supply undervoltage events, the LDO must be powered from a separate supply voltage other than the VSP supply. See Section 2.6 for more details.
