Circuit description
The L9332 is a quad low side driver for inductive loads like valves in automotive
environment. The internal pull down current sources at the ENable and INput pins assure in
case of open input conditions that the device is switched off. An output voltage slope
limitation for du/dt is implemented to reduce the EMI. This is valid up to the clamping voltage
V . This active flyback voltage limitation clamps the output voltage during the flyback phase.
Z
It is alowed to connect two power stages from one device in parallel if external free wheeling
diodes are used in the application. For the R calculation the parallel resistivity is expected.
on
The nominal current is 70% of the sum of the nominal currents of the used channels.
Each driver is protected against short circuit at V
< 32 V and thermal overload. In short
OUT
circuit condition the output will be disabled after a short delay time t . The thermal disable
D
for T > 175°C of the output will be reset if the junction temperature decreases about 20 °C
J
below the disable threshold temperature.
The overtemperature, overload and groundloss information is stored until IN is low.
For the real time error diagnosis the voltage and the current of the outputs are compared
with internal fixed values V
in OFF and ON conditions.

OUV
OUC
The diagnostic output level in connection with different ENable and INput conditions allows
to recognize different fail states, like overtemp, short to V , short to GND, bypass to GND
S
and disconnected load (see diagnostic table).
The diagnostic output is protected against short circuit. Exceeding the over load current
threshold I
, the output current will be limited internally during the diagnostic overload

delay switch-off time t .
D
The device complies the ISO pulses imposed to the supply voltage of the valves without any
failures of the functionality. Therefore some diagnostic functions are internal filtered. The
diagnostic table shows the corresponding filter time for each detected signal.
