INTERRUPTS
Operation can be controlled by the PWMIN input.
HS1 switch can be configured for cyclic sense operation in Stop mode.
HS1 switch can be configured for cyclic sense operation in Sleep mode.
Windowing operation when enabled by an external resistor.
High-voltage Interrupt:
Interrupts are used to signal a microcontroller that a
peripheral needs to be serviced. The interrupts which can be
generated, change according to the operating mode. While in
Normal and Normal Request modes, the 33911 signals
through interrupts special conditions which may require a
MCU software action. Interrupts are not generated until all
pending wake-up sources are read in the Interrupt Source
Register (ISR).
While in Stop mode, interrupts are used to signal wake-up
events. Sleep mode does not use interrupts. Wake-up is
performed by powering-up the MCU. In Normal and Normal
Request mode the wake-up source can be read by SPI.
The interrupts are signaled to the MCU by a low logic level of
the IRQ pin, which will remain low until the interrupt is
acknowledged by a SPI read command of the ISR register.
The IRQ pin will then be driven high.
Interrupts are only asserted while in Normal, Normal Request
and Stop mode. Interrupts are not generated while the RST
pin is low.
The following is a list of the interrupt sources in Normal and
Normal Request modes. Some of these can be masked by
writing to the SPI - Interrupt Mask Register (IMR).
Signals when the supply line (VS1) voltage increases above
the VSOV threshold ( V SOV ).
Over-temperature Prewarning:
Signals when the 33911 temperature has reached the pre-
shutdown warning threshold. It is used to warn the MCU that
an over-temperature shutdown in the main 5.0 V regulator is
imminent.
LIN Over-temperature Shutdown / TXD Stuck At
Dominant / RXD Short-circuit:
These signal fault conditions within the LIN interface will
cause the LIN driver to be disabled. In order to restart the
operation, the fault must be removed and TXD must go
recessive.
High Side Over-temperature Shutdown:
Signals a shutdown in the high side output.
Low Side Over-temperature Shutdown:
Signals a shutdown in the low side outputs.
Low-voltage Interrupt:
Signals when the supply line (VS1) voltage drops below the
VSUV threshold ( V SUV ).
