Thermal Protection and Monitoring
An on-chip temperature sensor provides two thresholds
of temperature monitoring.
If the device reaches the lower threshold, the nOVRT
output is asserted, providing warning indication to an
external controller. The low threshold setting provides
indication only, and does not have any effect on device
operation.
The lower high-temperature threshold (warning) is
set at approximately +125°C.
If the device reaches the higher threshold, it will drive all
four nERRORA-D outputs low (active) and shut down the
device, in addition to asserting the nOVRT output. This
shutdown in non-latching, and operation will resume
automatically when temperature returns to normal.
The higher high-temperature threshold (over-temp)
is set at approximately +140°C.
Power Supply Voltage Monitoring
Undervoltage monitors are included for the output drive
(HVDD) supply voltage, the on-chip generated gate drive
(REG5V) supply voltage, and the low-level PWMVDD
supply voltage. Detection occurs at approximately 2.5V
for PWMVDD, approximately 4V for the gate drive supply,
and approximately 7V for the HVDD supply. (Limits are
listed in the electrical specification tables starting on
If any of the monitored voltages drop below their
threshold, the device shuts down its outputs and asserts
all four of the nERROR outputs. Operation resumes
normally after the undervoltage condition is cleared.
