PROTECTED

QUAD POWER DRIVER

Providing improved output current limiting, the UDK, UDN, and

UDQ2559B, EB, and LB quad power drivers combine AND logic

gates and high-current bipolar outputs with complete output protection.

Each of the four outputs will sink 700 mA in the on state. The outputs

have a minimum breakdown voltage (load dump) of 60 V and a

sustaining voltage of 40 V. The inputs are compatible with TTL and

5 V CMOS logic systems.

Over-current protection for each channel has been designed into

these devices and is activated at approximately 1 A. It protects each

output from short circuits with supply voltages up to 25 V. When an

output current trip point is reached, that output stage is driven linearly

resulting in a reduced output current level. If an over-current or short-

circuit condition continues, the thermal-limiting circuits will first sense

the rise in junction temperature and then the rise in chip temperature,

further decreasing the output current. Under worst-case conditions,

these devices will tolerate short circuits on all outputs, simultaneously.

These devices can be used to drive various loads including incan-

descent lamps (without warming or limiting resistors) or inductive

loads such as relays, solenoids, or dc stepping motors.

The suffix ‘B’ devices are 16-pin power DIPs, the suffix ‘EB’

devices are 28-lead power PLCCs and suffix ‘LB’ devices are 16-lead

power SOICs for surface-mount applications. All three packages are

of batwing construction to provide for maximum package power

dissipation.
