Order Codes Part Number L9929 L9929XP Package PowerSO20 PowerSSO24 ■ ■ ■ ■ ■ ■ The H-Bridge is protected against over temperature and short circuits and has an under voltage lockout for all the supply voltages "VS" (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.
■ ■ 2 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.
