4. Instead of the switches shown in schematic, a chip is required to perform high current, high speed switching (5.1KHz).
Darlington drivers loose voltage across them when switching, look it up on the data sheet. Use a MOSFET.
Schematic is as follow;http://forum.allaboutcircuits.com/image_cache/httpi49.tinypic.com2589v0h.pngQuestions:A. What kind of chip/chip-array is best suitable for this type of applications? Darling array, P channel MOSFET etc..??B. Can following ICs be used for this application? UDN2981A (Would this ICs work with 5V supply voltage (Vs) ?) DMP2240UDM Please advice...
Following is my project brief:
QuoteFollowing is my project brief:You should try to use the mcu to control the "current sink driver", not supplying current to the current sink driver through the load.
