PROTECTED

QUAD POWER DRIVERS

Providing interface between low-level logic and power loads, the

UDK/UDN/UDQ2547B and UDK/UDN/UDQ2547EB quad power

drivers combine 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 and include internal

pull-down resistors to ensure that the outputs remain OFF if the inputs

are open-circuited.

Over-current protection for each channel has been designed into

these devices and is activated at approximately 1.3 A. It protects each

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

maximum driver output current is reached, that output drive is reduced

linearly, maintaining a constant load current. If the over-current or

short circuit condition continues, each channel has an independent

thermal limit circuit which will sense the rise in junction temperature

and turn OFF the individual channel that is at fault. Foldback circuitry

decreases the output current if excessive voltage is present across the

output and assists in keeping the device within its SOA (safe operating

area).

Each output also includes diagnostics for increased device protec-

tion. If any output is shorted or opened, the diagnostics can signal the

controlling circuitry through a common FAULT pin.

ABSOLUTE MAXIMUM RATINGS

at T_A= 25°C

Output Voltage, V_OUT............................ 60 V

These devices can be used to drive various resistive loads includ-

ing incandescent lamps (without warming or limiting resistors). With

the addition of external output clamp diodes, they can be used to drive

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

Over-Current Protected Output Voltage,

V_OUT............................................... 25 V

Output Current, I_OUT.......................... 1.3 A*

FAULT Output Voltage, V_F................... 40 V

Supply Voltage, V_CC............................ 7.0 V

Input Voltage, V_INor V_EN...................... 7.0 V

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.

■ Output SOA Protection

■ Low Output-Saturation Voltage

■ Independent Over-Current Protection for Each Driver

■ Independent Thermal Protection for Each Driver

■ 600 mA Output Current per Channel

T_S............................... -55°C to +150°C

*Outputs are current limited at approximately

1.3 A per driver and junction temperature limited

if current in excess of 1.3 A is attempted. See

Circuit Description and Application for further

information.

Always order by complete part number: a prefix to indicate operat-

ing temperature range + the basic four-digit part number + a suffix to

indicate package style, e.g., UDK2547EB .
