TLC555-Q1: Source current limits

Part Number: TLC555-Q1

Dear Support Team

my customer is requesting if we have a characterization of source current over temp, and/or if we have an alternative device Q1 with more output current capability

the purpose is to generate a PWM controlled by the value of an NTC

Please let me know if you have any suggestion or any other creative approach

thanks

Kind Regards

Nicola

  • Nicola,

    Higher supply voltage improves the VOH drive current. 

    Here is sample data for VOH vs IOH

    Why does the load need more current?

    Thanks Ron,

    customer actually needed exactly the characterization above, with 12V they should be fine.

    Thanks for your support

    Kind Regards
