DS3669 Quad High Current Peripheral Driver

General Description

Stepping motor drivers

Triac drivers

The DS3669 is a non-inverting quad peripheral driver similar

to the DS3658. These drivers are designed for those appli-

cations where low operating power, high breakdown volt-

age, high output current and low output ON voltage are re-

quired. A unique input circuit combines TTL compatibility

with high impedance. In fact, its extreme low input current

allows it to be driven directly by a CMOS device.

LED drivers

High current, high voltage drivers

Level translators

Fiber optic LED drivers

The outputs are capable of sinking 600 mA each and offer a

70V breakdown. However, for inductive loads the output

should be clamped to 35V or less to avoid latch-up during

turn off (inductive fly back protectionÐrefer AN-213). An on-

chip clamp diode capable of handling 800 mA is provided at

each output for this purpose. In addition, the DS3669 incor-

porates circuitry that guarantees glitch-free power up or

down operation.

Features

Single saturated transistor outputs

Low standby power, 10 mW typical

High impedance TTL compatible inputs

Outputs may be tied together for increased current

capacity

High output current

600 mA per output

2.4A per package

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 PC board, the power rating of the device

improves significantly.

No output latch-up at 35V

Low output ON voltage (350 mV typ 600 mA)

High breakdown voltage (70V)

Open collector outputs

Output clamp diodes for inductive fly back protection

NPN inputs for minimal input currents (1 mA typical)

Low operating power

Applications

Lamp drivers

Standard 5V power supply

Power up/down protection
