13 VDHOV

VDH overvoltage flag

This flag is set and latched as soon as an overvoltage is detected on VDH supply. It can be cleared by SPI only

if the source of the fault is no longer present. Automatically cleared at first valid SPI communication frame

12 VDHUV

VDH undervoltage flag

This flag is set and latched as soon as an undervoltage is detected on VDH supply. It can be cleared by SPI

only if the source of the fault is no longer present. Automatically cleared at first valid SPI communication frame

11 VDDOV

VDD overvoltage fault flag

This flag is set and latched as soon as an overvoltage is detected on VDD supply. It can be cleared by SPI only

if the source of the fault is no longer present. Automatically cleared at first valid SPI communication frame

Thermal warning flag

This flag is set and latched as soon as device junction temperature exceeds TW threshold for a time longer

than the corresponding filter time. It can be cleared by SPI only if the source of the fault is no longer present.

Automatically cleared at first valid SPI communication frame

TSD

Thermal shutdown flag

This flag is set and latched as soon as device junction temperature exceeds TSD threshold for a time longer

than the corresponding filter time. It can be cleared by SPI only if the source of the fault is no longer present.

Automatically cleared at first valid SPI communication frame

DIAGCR

DIAGN flag

This flag is set as soon as the DIAGN pin is activated. It is automatically cleared as soon as the DIAGN is de-

activated
