#91223 - Pull Ups and Base Current Responding to: ???'s previous message |
With 10K pullups you will get no more than 0.5mA base current into the 2N2222. A typical saturated current gain for this transistor will be in the region of 20 so your load current should not exceed 10mA. If you need more load current you need to reduce the pullups.
