TPL7407L: Current Rating for GND Pin

Part Number: TPL7407L
Other Parts Discussed in Thread: ULN2003A

In the D/S, it says the ground pin current of this device can only be rated up to 2A. It means that the every channel  of this device can not be working with 600mA,avg current at the same time, correct? 

Is there any 4CH or 8CH low side switch integrated? Thanks.

Regards

Brian

  • Hi Brian,

    Thanks is correct, if you look at the waveforms on page page of the datasheet (Figure 4, 5 ,6), you can see the maximum collector current vs temperature and duty cycle based on the number of channels used.

    We have the ULN2803A for an 8-ch low side switch, but we don't have any 4-ch LSS. The ULN2003A can support higher collector currents, but is only available as a 7-ch LSS.

    Thanks,

    Arthur Huang
