1.5A DUAL OPEN-DRAIN MOSFET DRIVERS

FEATURES

GENERAL DESCRIPTION

■ Independently-Programmable Rise and Fall Times

■ Low Output Impedance ................................ 7Ω Typ

■ High Speed t_R, t_F....... <30 nsec with 1000 pF Load

■ Short Delay Times ....................................< 30 nsec

■ Wide Operating Range ..........................4.5V to 18V

■ Latch-Up Protected ......... Will Withstand >500 mA

Reverse Current (Either Polarity)

The TC4404 and TC4405 are CMOS buffer-drivers

constructed with complementary MOS outputs, where the

drains of the totem-pole output have been left separated so

that individual connections can be made to the pull-up and

pull-down sections of the output. This allows the insertion

of drain-current-limiting resistors in the pull-up and/or pull-

down sections, allowing the user to define the rates of rise

and fall for a capacitive load; or a reduced output swing, if

driving a resistive load, or to limit base current, when

driving a bipolar transistor. Minimum rise and fall times,

with no resistors, will be less than 30 nsec for a 1000-pF

load. There is no upper limit.

For driving MOSFETs in motor-control applications,

where slow-ON/fast-OFF operation is desired, these de-

vices are superior to the previously-used technique of add-

ing a diode-resistor combination between the driver output

and the MOSFET, because they allow accurate control of

turn-ON, while maintaining fast turn-OFF and maximum

noise immunity for an OFF device.

When used to drive bipolar transistors, these drivers

maintain the high speeds common to other TelCom driv-

ers. They allow insertion of a base current-limiting resistor,

while providing a separate half-output for fast turn-OFF. By

proper positioning of the resistor, either npn or pnp transis-

tors can be driven.

For driving many loads in low-power regimes, these

drivers, because they eliminate shoot-through currents in

the output stage, require significantly less power at higher

frequencies, and can be helpful in meeting low-power

budgets.

Because neither drain in an output is dependent on

the other, these devices can also be used as open-drain

buffer/drivers where both drains are available in one device,
