■

The H-Bridge is protected against over tempera-

ture and short circuits and has an under voltage

lockout for all the supply voltages "V

" (Main DC

power supply). All malfunctions cause the output

stages to go tristate.

The H-Bridge contains integrated free-wheel di-

odes. 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.

■

Description

The L9929 is an SPI controlled H-Bridge, de-

signed for the control of DC and stepper motors in

safety critical applications and under extreme en-

vironmental conditions.
