Hi, I’m trying to drive 16 parallel 3V 120mA motors with TLC5940 in conjunction with 2N2222 transistors and a 3.7V external source but couldn’t get even 1 motor running. The referenced circuit is mentioned in a TI’s report http://www.tij.co.jp/jp/lit/an/slva280/slva280.pdf on page 5. It suggests a…
