ABSOLUTE MAXIMUM RATINGS
at +25°C Free-Air Temperature
Supply Voltage Range, VS ..... 10 V to 60 V
Output Current, IOUT
(continuous) ............................... -4.0 A
(peak) ......................................... - 5.0 A
Input Voltage, VIN ................................ 15 V
Package Power Dissipation,
PD ....................................... See Graph
Operating Temperature Range,
TA ................................ -20°C to +85°C
Storage Temperature Range,
TS .............................. -55°C to +150°C
Output current rating will be limited by
ambient temperature, duty cycle, heat
sinking, air flow, and number of outputs
conducting. Under any set of conditions, do
not exceed the -5.0 A peak current or a
junction temperature of +150°C.
QUAD HIGH-CURRENT,
HIGH-VOLTAGE SOURCE DRIVER
Capable of driving loads to 4 A at supply voltages to 60 V (induc-
tive loads to 35 V), the UDN2944W is a quad high-current, high-
voltage source driver. Each of the four power drivers can provide
space- and cost-saving interface between low-level signal-processing
circuits and high-power loads in harsh environments.
Individual supply lines have been provided for each pair of drivers
so that different supplies can be used to drive multiple loads. The
controlling inputs are TTL or CMOS compatible. The outputs include
transient-suppression diodes for inductive loads.
This quad Darlington array is designed to serve as an interface
between low-level circuitry and peripheral-power loads such as sole-
noids, motors, incandescent displays, heaters, and similar loads of up to
240 W per channel. The UDN2944W is an ideal complement to the
UDN2878W quad 4 A sink driver.
For maximum power-handling capability, the UDN2944W driver
is supplied in a 12-pin single in-line, power-tab package that allows
efficient attachment of an external heat sink for maximum allowable
package power dissipation. An external heat sink is usually required
for proper operation of this device. The tab is at ground potential and
needs no insulation.
