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.

L9230-DIE1
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 sup-
ply). 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 tran-
sistor 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.

Note: 1. In case of SC OUTx to Vs the switch off current is always higher than the start value of current regulation (|IOUK| = |IOUK| - |IOUmax|
2. Guaranteed by design
3. Value is tested down to 6V. For supply voltage below 6V on increased current can be fed back in the device via a protection path

1.) In case of undervoltage tristate and status-flag are reset automatically.
2.) Whenever overcurrent or overtemperature is detected, the fault is stored (i.e. status-flag remains low).
The tristate conditions and the status-flag 3) are reset via DI or EN.
