Just not sure what i do with my driver having one more pin than the one in the toturial. The outputs are capable of sinking mA and will withstand at least V in the off state. JYelton Thanks for the feedback! Details, datasheet, quote on part number: Typical power loads totaling over 95 V can be controlled at an appropriate duty cycle depending on ambient temperature and number of drivers turned on simultaneously.

ULN datasheet –

I’ve edited several other questions with this issue. Only in this circuit, you’d have in8out8 pins setup the same as in7 and out7.

See matrix on next page. You can find many tutorials online. All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout.

It might’ve been a uln284 mistake derived from laziness since the chips have the same type of circuitries. Because these chips are practically the same, you can utilize the same way as These chips are commonly use for this application.

All devices feature open-collector outputs with integral clamp diodes. High Voltage 3 Phase Motor Drivers The SCMM series IPM Inverter Power Module device provides a robust, highly-integrated solution for optimally controlling 3-phase motor power inverter systems and variable speed control systems used in energy-conserving designs to drive motors of residential.

uln204 Characteristic shown applies to family of devices with remaining digits as shown. Iancovici 1, 10 It looks like the same application and same specs, set of darlington arrays. Note that the ULx28xxA series dual in-line package and ULx28xxLW series smalloutline IC package are electrically identical and share a common terminal number assignment.

I have an unipolar stepper motor that im driving with an Arduino. This example looks fine.

Thanks for your efforts! So, can it work to power my stepper? I’m not experienced enough to make up my own sheet completely on my own. Specification shown applies to family of devices with remaining digits as shown. And how do i alter the sketch to work with an extra pin on the chip?

I might be missing something, but the chip i received has 9 pins on each side, not 8 as my sketch illustrates, and the number on it is ULN, not ULN As a driver for the motor i bought a ULN driver chip from Ebay.

How do i then change my sketch to implement the last two additional pins of the chip?
