DS3669 Quad High Current Peripheral Driver General Description The DS3669 is a non-inverting quad peripheral driver similar to the DS3658. These drivers are designed for those applications where low operating power, high breakdown voltage, high output current and low output ON voltage are required. 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. 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 onchip clamp diode capable of handling 800 mA is provided at each output for this purpose. In addition, the DS3669 incorporates circuitry that guarantees glitch-free power up or down operation. The molded package is specifically constructed to allow increased 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.

They are not meant to imply that the device should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation. Note 2: Unless otherwise specified, min/max limits apply across the 0§ C to a 70§ C temperature range and the 4.75V to 5.25V power supply range. All typical values are for TA e 25§ C and VCC e 5.0V. Note 3: All currents into device pins are shown as positive; all currents out of device pins are shown as negative; all voltages are referenced to ground, unless otherwise specified. All values shown as max or min are so classified on absolute value basis. Note 4: All sections of this quad circuit may conduct rated current simultaneously; however, power dissipation averaged over a short interval of time must fall within specified continuous dissipation ratings. Note 5: For operation over 25§ C free-air temperature, derate linearly to 1328 mW 2 @ 70§ C @ the rate of 16.6 mW/§ C.
