Motor Drivers Provide DMOS Outputs

The A3972 and A3973 are serial controlled micro-stepping drivers with all N-channel DMOS outputs. And they are said to offer decreased power dissipation and higher current capability compared to bipolar drivers. The A3972SB combines low- voltage CMOS logic, bipolar control circuits, and power DMOS transistors on a single chip. The device is capable of output currents up to ±1.5A and operating voltage is to 50V. The A3973 is a pin-for-pin compatible device designed for lower voltage applications. Package options include a 24-lead bat-wing DIP for the A3972 and a 24-lead DIP or SOIC for the A3973. Pricing is $2.65 and $2.15, respectively, each/50,000.
