2944 General Description

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.

2944666661 General Description

The 2944666661 is a type of quad high-current,high-voltage source driver.The 2944666661 is Capable of driving loads to 4 A at supply voltages to 60 V.Every four power drivers can offer space- and cost-saving interface between low-level signal-processing circuits and high-power loads in harsh environments. Individual supply lines have been offered for each pair of drivers so that different supplies can be applied to drive multiple loads. The charging inputs are TTL or CMOS compatible. The outputs include transient-suppression diodes for inductive loads. This quad Darlin gton array is aimed to serve as an interface between low-level circuitry and peripheral-power loads such as solenoi ds, motors, incandescent displays, heaters, and similar loads of up to 240 W per channel.

The 2944666661 has the following features:(1)output current to 4 A;(2)output voltage to 60 V;(3)loads to 960 W;(4)integral output suppression diodes;(5)TTL and CMOS compatible inputs;(6)plastic single in-line package;(7)heat-sink tab.

It also has some outstanding absolute maximum ratings(at +25°C free-air temperature) and electrical characteristi cs (TA = +25°C, TJ +150°C, VS = 60 V, VENABLE = 0 V).Absolute maximum ratings:(1):Supply Voltage Ranges from 10 V to 60 V;(2):output current is -4.0 A(continuous),output current is -5.0 A(peak);(3)input voltage is 15 V;(4):operating temperature ranges from -20°C to +85°C;storage temperature ranges from -55°C to +150°C. elec trical characteristics:(1):supply voltage ranges from 10V min to 60 V max;(2):output leakage current is 50 uA max when VOUT is 0 V and VENABLE is 2.4 V;(3):output sustaining voltage is 35 V when IOUT is -4 A and L is 3 mH;(4): output saturation voltage is 1.8 V max when IOUT is -1 A and VIN is 2.4 V;(5):input voltage is 2.0 V min when of VIN(1) or VENABLE;(6):input Current is 220 uA when VIN(1) or VENABLE(1) is 2.4 V;(7):total supply current is 25 mA of drivers on when All outputs is open;(8)clamp diode leakage current is 50 uA when VR is 60 V.
