#157510 - Low-power mode? Responding to: ???'s previous message |
Do you need to turn off the power to the #2 guy? If it has any proper power-save modes, it might be enough to give it a message that it should set all I/O pins in optimum low-power states and then enter the best low-power mode supported.
Just turning off the power to a chip does not guarantee a low power consumption. The I/O pins may still sink current from pull-ups or other chips on the board. |

Perhaps you should try a logic-MOSFET | 01/01/70 00:00 | |
It Still Makes No Difference | 01/01/70 00:00 | |
Maybe it's the load current | 01/01/70 00:00 | |

I wouldn't say that ... | 01/01/70 00:00 | |
