Table 2. Pin definitions and functions

Pin Symbol Function

1, 18, 19, 36 GND

Ground:

Reference potential

Important: for the capability of driving the full current at the outputs all

pins of GND must be externally connected.

2, 35 OUT8

Highside driver output 8

The output is built by a highside switch and is intended for resistive

loads, hence the internal reverse diode from GND to the output is

missing. For ESD reason a diode to GND is present but the energy

which can be dissipated is limited. The highside driver is a power

DMOS transistor with an internal parasitic reverse diode from the

output to VS (bulk-drain-diode). The output is over-current and open

load protected.

Important: for the capability of driving the full current at the outputs both

pins of OUT8 must be externally connected.

OUT1

OUT2

OUT3

Half-bridge-output 1,2,3

The output is built by a highside and a lowside switch, which are

internally connected. The output stage of both switches is a power

DMOS transistor. Each driver has an internal parasitic reverse diode

(bulk-drain-diode: highside driver from output to VS, lowside driver from

GND to output). This output is over-current and open load protected.

* Note: Value of capacitor has to be choosen carefully to limit the VS voltage below absolute

maximum ratings in case of an unexpected freewheeling condition (e.g. TSD, POR)

** Note: Resistors between µC and L9953 are recommended to limit currents

for negative voltage transients at VBAT (e.g. ISO type 1 pulse)
