PROTECTED  
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.
