Other Parts Discussed in Thread: TUSB1310

Hi Everyone,

Please let me know the detail of power up and down sequence. I'd like to know which supply should be input first. Or is there no requirement between VDD1P1, VDD1P8, VDDA1P1, VDDA1P8 and VDDA3P3.

Best Regards,

Sonoki / Japan Disty

    Hello Sonoki,

    All TUSB1310 analog and digital power terminals must be controlled during the power-up and power-down sequence. Absolute maximum power terminal ratings must not be exceeded to prevent damaging the device. There is no requirement on which power rail be applied first nor does it matter which rail is removed first.

    Regards,

    Gerardo
