FUNCTIONAL DESCRIPTION
General
The L9903 integrated circuit (IC)is designed to control four external N-channel MOS transistors in H-Bridgecon-
figuration for DC-motor driving in automotive applications. It includes an ISO9141 compatible interface. A typical
application is shown in fig.6.
Voltagesupply
The IC is supplied via an external reverse battery protection diode to the V
VS
pin. The typical operating voltage
range is down to 8V.
Extended supply voltage range (ST)
The operating battery voltage range can be extended down to 6V using the additional components shown in
fig.7. A small inductor of L~150
μ
H (I
peak
~500mA) in series to the battery supply builts up a step up converter
with the switching open drain output ST. The switching frequency is typical 100kHz with a fixed duty cycle of
50%. The step up converter starts below V
VS
< 8V, increases the supply voltage at the VS pin and switches off
at V
VS
> 10V to avoid EME at nominal battery voltage. The diode D2 in series with the ST pin isnecessary only
for systems with negative battery voltage. No additional load can be driven by the step up converter.
