Also from datasheet's paragraph 9: "Though 8.5 V minimum is recommended for Vcom, the part will still function with a reduced COM voltage that has a reduced gate drive voltage and a resulting higher Rdson" --- End quote --- It would be nice if there was a graph of the on resistance vs power supply voltage, on the data sheet. |

Toshiba has IC operating as low as 2V: TBD62783APG Long list sourcing/ sinking types, MIN voltage 2V, 2.5V, 3V, 7V: https://www.mouser.ca/Toshiba/Semiconductors/Power-Management-ICs/Gate-Drivers/_/N-41fcp?P=1z0zkx4 |
| Evan.Cornell:
Take a look at Toshiba TBD62003A. Similar idea to TI TPL7404L (FETs instead of Darlingtons), but without the 8.5V requirement. |
| JPortici:
Diodes inc make a ULN2003 compatible that uses logic level mosfets, i used it in a project some months ago |
| koendv:
tpl7407ldr. Texas Instruments. Plug-in compatible. |
