QUAD POWER DRIVER
Providing improved output current limiting, the UDK/UDN/
UDQ2549B and UDK/UDN/UDQ2549EB quad power drivers combine
AND logic gates and high-current bipolar outputs with complete output
protection. Each of the four outputs will sink 600 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,
the six devices in this family will tolerate short-circuits on all outputs,
simultaneously.
These devices can be used to drive various loads including
incandescent 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 while the suffix ‘EB’
devices are 28-lead power PLCCs for surface-mount applications.
Both packages are of batwing construction to provide for maximum
package power dissipation.
