NSD5604 / NSD5604N
4-channel Low Side Driver
Datasheet (EN) 1.5
Integrated protection
Product Overview
Overcurrent / short circuit protection
The NSD5604 / NSD5604N is a 4-channel low side driver
for industrial and automotive applications including
programmable logic control, general relays, or other
solenoid drivers.
Both common thermal and per channel over
temperature protection
VM Input undervoltage protection
Dedicated nFault indicator pin
The device includes 4x parallel input interface, which
controls 4x independent driving outputs for resistive,
inductive, or capacitive loads. The output channels can
be parallelized to support high current load and reduce
device power dissipation. Low side outputs are
protected against over temperature and short circuit.
The integrated diodes clamp the voltage transients
generated during inductive loads turning off; combined
with different external TVS connection topologies, slow
decay or fast decay turn-off can be implemented.
NSD5604 also features an additional 5V max 20mA LDO
output for on board digital isolator or photo coupler
power supply.
