TYPICAL APPLICATIONS
STANDALONE MODE
STANDALONE MODE
This section consists of evaluating the MC33580
standalone capability.
CONFIGURATION WITHOUT MCU
The standalone mode is intended for customers who
desire to plug the device and then immediately “play” with it,
without having to connect it to a microcontroller. It also
provides an easy way to evaluate the main electrical features.
Without the Microcontroller to select programmable
parameters and get full diagnosis via the SPI, the MC33580
runs with all parameters set to default.
The input SPI pin pins and VDD must be connected to
ground. Fail safe mode and watchdog timeout must be
disabled by connecting the FSI to GND.
All protection functions are available without SPI
communication. Nevertheless, any configuration is possible
Table 18. Available Functions
without an MCU to communicate by SPI. Some functions still
enable, but diagnosis is reduced. Available functions and
default parameters are detailed next.
FUNCTIONING WITHOUT MCU
Without an MCU, SPI communication is not possible. Fail
safe mode and watchdog timeout are not useful functions
without an MCU, but still enable. Wake/Sleep mode is used
to minimize current consumption during sleep mode. IN pins
control the corresponding outputs and FS output is active (at
0 V) when a default occurs.
Table 18 illustrates the available functions without SPI and
default parameters.
Table 19 illustrates default parameters after resetting or
applying supply voltage to the MC33580. Levels and timings
are typical values.
