L9346

CIRCUIT DESCRIPTION

The L9346 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 conditionsthat the device is switched off. An
output voltage slope limitation for du/dt is imple­mented to reduce the EMI. An integrated active
flyback voltage limitation clamps the output volt­age during the flyback phase to 50 V.

Each driver is protected against short circuit at

OUT < 32V and thermal overload. In short circuit

V
condition the output will be disabled after a short

DOL

delay time t

. The thermal disable for TJ >
180°C of the output will be reseted if the junction
temperaturedecreasesabout 20°Cbelow the dis­able threshold temperature.
Theov er temperatureinformationisstoreduntilIN=L.

For the real time error diagnosis the voltage and
the current of the outputs are compared with in­ternal fixed values V
conditions to recognize open load (R
R

L >38Ω) in OFFand ON conditions.

Also the output voltages V

OUV for OFF and IOUC for ON

L ≥ 20 KΩ,

- 4 are compared to

each other output in OFF condition with a fixed

offset of ∆V
suppress the ∆V

OUV to recognize load bypasses. To

OUV diagnoses duringthe flyback

phases of thecomparedoutput, the∆VOUVdiag­nostic includesa latch function.

Reaching the flyback clamping voltage V

OCL the

diagnostic signalisresetedby a latch. To activate
again this kind of diagnostic a low signal at the
correspondent INPUT or the ENABLE pin must
be applied (see also Fig.3). The outputs 1 and 4
are compared for ∆V

OUV and also outputs 2 and 3

are compared.
The diagnosticoutput level in connectionwith dif-

ferent ENABLE and INPUT conditions allows to
recognize differentfailstates,like overtemp,short

SS, short to GND, bypass to GND and dis-

to V
connectedload (see diagnostictable).

The diagnostic output is protected against short
circuit. Exceeding the over load current threshold

OOC

, the output current will be limited internally

I
during the diagnostic overload delay switch-off
time t

DOL.

The device complies the ISO pulses imposed to
the supply voltage of the valves without any fail­ures of the functionality.
