MC1413 - High Voltage, High Current Darlington Transistor ...
www.onsemi.comDarlington Transistor Arrays The seven NPN Darlington connected transistors in these arrays are well suited for driving lamps, relays, or printer hammers in a variety of industrial and consumer applications. Their high breakdown voltage and internal suppression diodes insure freedom from problems associated with inductive loads.

eeshop.unl.eduThe ULN2003A contains seven darlington transistor drivers and is somewhat like having seven TIP120 transistors all in one package. The ULN2003A can pass up to 500 mA per channel and has an internal voltage drop of about 1V when on. It also contains internal clamp diodes to dissipate voltage spikes when

It re-ceives step clock, direction and mode signals from the systems controller (usually a microcomputer chip) and generates control signals for the power stage. The principal functions are a translator, which gen-erates the motor phase sequences, and a dual
CHAPTER 9: POWER MANAGEMENT - Analog Devices
www.analog.comthis increase is the reduction of size of the transistors used in the process. These smaller feature sizes imply lower breakdown voltages, which, in turn, indicate lower supply voltages. Another trend in power management is the often misguided attempt to operate the analog and digital circuitry on the same supply, eliminating one of the supplies.
