Maximum rating for junction temperature
Overtemperature switch-off
Switch-off current in case of current limitation
For typical 165°C < Tj < 175°C the maximum current decreases

Spi Interface
The timing of L9929 is defined as follows:
- The change at output (SO) is forced by the rising edge of the SCK signal.
- The input signal (SI) is taken over on the falling edge of the SCK signal.
- SS = active without any clocks at SCK is not allowed
- The data received during a writing access is taken over into the internal registers on the rising edge of the SS
signal, if exactly 16 SPI clocks have been counted during SS = active.
