TYPICAL APPLICATIONS

DIAGNOSIS WITHOUT MCU
When any fault appears (over current, open load…), a full
diagnosis can be reported via the SPI. Without an MCU, the

H : High Level, L : Low Level, Z : High impedance, potential depends on the external circuit.
We can note that it is not possible to distinguish over
temperature, over current, under voltage, and over voltage.
Nevertheless, Open load and short circuit to V PWR fault can
be singled out. All protections are reported to Fault status pin
(FS), Open load and short circuit to V PWR are reported only if
the Output is OFF. If the fault is latched, the output must be
turned OFF then ON to disable the fault.
functioning is safe because all protections are available.
Diagnosis is limited, but the fault status pin will report any
malfunction.
This is a good way to evaluate the main electrical
MC33580 features. Some simplified applications can also
use the MC33580 switch without an MCU to drive a high
power load with full protection.
CONCLUSION
Although the MC33580 is not fully functional without a
microcontroller to control and program it, standalone
