Other Parts Discussed in Thread: TPIC6B595
Hi,
I wanted to confirm the current capability of TPIC6C596. It's mentioned in the sheet the peak drain current-single output is 250mA with a pulse duration of 100us and 2% duty cycle while the continuous drain current, each output, all outputs on is 100mA. Here's the datasheet info:
So I want to know:
1. How much continuous current can I draw only from one output? I know the peak can be 250mA but I want to know the continuous current value only for one output.
2. Also, the continuous drain current, has a note saying that the pulse duration <= 100 microseconds and duty cycle <= 2%? The pulsed drain current, each output, all outputs on is 250 mA also has the same note.
I do not understand why both the continuous drain current and the pulsed drain current both have pulse duration and duty cycle limit. Only the pulsed drain current should have pulse duration limits. If I am wrong, can you explain what's the difference between pulsed and continuous drain current with respect to the driver?
3. Also, is there a way I can test the functionality of the driver to check if it's properly switching the outputs according to the serial input that I provide before I connect in my main circuit?
Thank you for your help.
