Description
Over-temperature on any gate drive output generates an interrupt if this bit is set.
Desaturation event on any output generates an interrupt if this bit is set.
VLS under-voltage generates an interrupt if this bit is set.
Over-current Error –if the over-current comparator threshold is exceeded, an interrupt is generated.
Phase Error –if any Phase comparator output is not at the expected value when an output is command on, an interrupt is
generated. This signal is the XOR of the phase comparator output with the output drive state, and blacked for the duration
of the desaturation blanking interval.
In FULLON mode, this signal is blanked and cannot generate an error.
Framing Error –if a framing error occurs, an interrupt is generated.
Write Error after locking.
Reset Event –If the IC is reset or disabled, an interrupt occurs. Since the IC will always start from a reset condition, this can
be used to test the interrupt mechanism because when the IC comes out of RESET, an interrupt will immediately occur.
MODE COMMAND
This command is sent by sending binary 010x xxxx data.

? Bit 0 – Mode Lock is used to enable or disable Mode Lock. This bit can only be cleared with a device reset. Since the mode
Lock mode can only be set, this bit prevents any subsequent, and likely erroneous, mode, deadtime, or mask register
changes from being received. If an attempt is made to write to a register when Mode Lock is enabled, a Write Error fault
is generated.
? Bit 1 – FULLON Mode. If this bit is set, programmed deadtime control is disabled, making it is possible to have both high
and Low Side drivers in a phase on simultaneously. This could be useful in special applications such as alternator
regulators, or switched-reluctance motor drive applications. There is no deadtime control in FULLON mode. Input signals
directly control the output stages, synchronized with the internal clock.
This bit is a “0”, after RESET. Until overwritten, the IC operates normally; deadtime control and logic prevents both outputs
from being turned on simultaneously.
? Bit 3 – Desaturation Fault Mode controls what happen when a desaturation event is detected. When set to “0”, any
desaturation on any channel causes all six output drivers to shutoff. The drivers can only be re-enabled by executing the
CLINT command. When 1, desaturation faults are completely ignored.
Bit 3 controls behavior if a Desaturation, or Phase Error event is detected. The possibilities are:
— 0: Default: When a Desaturation, or Phase Error event is detected on any channel, all channels turn off and generates
an Interrupt, if interrupts are enabled.
— 1: Disable: Desaturation /Phase Error channel shutdown is disabled, but interrupts are still possible if unmasked.
Sending a MODE command and setting the Mode Lock simultaneously are allowed. This sets the requested mode and locks out any further
changes.
