DS3656 Quad Peripheral Driver
General Description
The DS3656 is a quad peripheral driver designed for use in
automotive applications Logically it is an open collector
NAND function with all inputs compatible with 74LS and
CMOS series products An enable input is provided that is
common to each driver When taken to a logic zero level all
outputs will turn off Also overvoltage is detected
The DS3656 has features associated with the output struc-
ture that make it highly versatile to many applications Each
output is capable of 600 mA sink currents and offers 65V
standoff voltage in non-inductive applications A clamp net-
work capable of handling 800 mA is incorporated in each
output which eliminates the need of an external network to
quench the high voltage backswing caused when switching
inductive loads up to 30V (reference AN-213)
The DS3656 is intended to operate from a 12V automotive
battery Internal to the device is its own voltage regulator
which permits the device to operate during the wide voltage
variation seen in many automotive applications An over-
voltage-protection circuit is incorporated that will cause the
outputs to turn off when the supply exceeds 30V The circuit
is designed to withstand worst case fault conditions that
occur in automotive applications such as high voltage tran-
sients and reverse battery connection In this type of envi-
ronment an external 100X resistor must be connected in
series with the VCC line
The molded package is specifically constructed to allow in-
creased power dissipation over conventional packages The
four ground pins are directly connected to the device chip
with a special copper lead frame When the quad driver is
soldered into a copper PC board the power rating of the
device will significantly improve
