MIC4604/4605

Dual 1.5A-Peak Open-Drain MOSFET Driver

Preliminary Information

General Description

The MIC4604 and MIC4605 are BiCMOS/DMOS buffer-

drivers constructed with complementary MOS outputs, where

the drains of the final output totem pole have been left

disconnected so individual connections can be made to the

pull-up and pull down sections of the output. This allows the

insertion of individual drain-current-limiting resistors in the

pull up and pull down sections of the output, thus allowing the

user to define the rates of rise and fall desired for a capacitive

load, or a reduced output swing if driving a resistive load, or

to limit base current when driving a bipolar transistor. Mini-

mum rise and fall times, with no resistors, will be less than

20ns for a 1000pF load. There is no upper limit.

These devices are rugged due to extra steps taken to protect

them from failures. A modern Bipolar/CMOS/DMOS process

guarantees freedom from latchup. Proprietary circuits allow

the input to swing negative as much as 5V without damaging

the part.

For driving MOSFETs in motor-control applications, where

slow on/fast off operation is desired, these devices are

superior to the previously used technique of adding a diode

resistor combination between the driver output and the MOS-

FET, because they allow accurate control of turn-ON, while

maintaining fast turn-OFF and maximum noise immunity for

an OFF device.
