Maximum Load Inductance
During demagnetization of inductive loads, energy has to be dissipated in the TLE7233G.
This energy can be calculated with following equation:
Following equation simplifies under the assumption of R
The maximum energy, which is converted into heat, is limited by the thermal design of the component.
6.3
The power transistors are switched on and off with a dedicated slope via the IN bits of the serial peripheral
interface SPI. The switching times t
Figure 7
In input mode, a high signal at the input pin is equivalent to a SPI ON command and a low signal to SPI OFF
command respectively. Please refer to
The listed switching times are not valid, when switching to or from stand-by mode.
