OUT2
Half-bridge output 2 (see OUT1 - pin 3, 4).
Note
: for the capability of driving the full current at the outputs all pins of
OUT2 must be externally connected.
20, 21
OUT3
Half-bridge output 3 (see OUT1 - pin 3, 4).
Note: for the capability of driving the full current at the outputs all pins of
OUT3 must be externally connected.
26
CP
Charge Pump Output
.
This output is provided to drive the gate of an external n-channel power
MOS used for reverse polarity protection (see Figure 1).
27
EN
Enable input.
If Enable input is forced to GND the device will enter Standby-Mode. The
outputs will be switched off and all registers will be cleared
33, 35
OUT4, OUT5
High side driver output 4, 5 .
The output is built by a high side 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 high side driver is a power DMOS
transistor with an internal reverse diode from the output to VS (bulk-
drain-diode). The output is over-current and open-load protected.
