L9929 General Description

The L9929 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 low side 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 voltage level of the according output-stage is below the ground-level. In this case it must be ensured, that the upper transistor is switched off.

L9929 Maximum Ratings

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.
