UDN2944

2944 QUAD HIGH-CURRENT, HIGH-VOLTAGE SOURCE DRIVER Capable of driving loads to 4 A at supply voltages to 60 V (inductive loads to 35 V), the UDN2944W is a quad high-current, highvoltage 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 solenoids, 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. Dwg. No. A-13,054 Data Sheet 29309.10† VS 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.
