L9230

The integrated circuit must not be destroyed by use at the limit values.
Each limit value can be used, as long as no other limit is violated.
Voltage reference point: All values are, if not otherwise stated, relative to ground.
Direction of current flow: Current flow into a pin is positive.
Rise-, fall- and delaytimes: If not otherwise stated, all rise times are between 10% and 90%, fall times
                                           between 90% and 10% and delay times at 50% of the relevant steps.

The L9230 is an SPI controlled H-Bridge, designed for the control of DC and stepper motors in safety critical applications and under extreme environmental conditions.

The H-Bridge is protected against over temperature and short circuits and has an under voltage lockout for all the supply voltages "V_S" (Main DC power supply). All malfunctions cause the output stages to go tristate.

The H-Bridge contains integrated free-wheel diodes. In case of free-wheeling condition, the lowside transistor is switched on in parallel of its diode to reduce the current injected into the substrate.

Switching in parallel is only allowed, if the voltagelevel of the according output-stage is below the ground-level.In this case L9230 must be ensured, that the upper transistor is switched off.
