L9230-DIE1

The H-Bridge is protected against over temperature

and short circuits and has an under voltage lockout

for all the supply voltages ”V ” (Main DC power sup-

ply). All malfunctions cause the output stages to go

tristate.

■ ENABLE AND DISABLE INPUT

■ SO20 POWER PACKAGE

The H-Bridge contains integrated free-wheel diodes.

In case of free-wheeling condition, the lowside tran-

sistor is switched on in parallel of its diode to reduce

the current injected into the substrate.

DESCRIPTION

The L9230 is an SPI controlled H-Bridge, designed

for the control of DC and stepper motors in safety crit-

ical applications and under extreme environmental

conditions.

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.
