TPS22976: ON1/ON2 input circuit and power up/down seq

Hironori Yoshimura
Intellectual 1850 points
Part Number: TPS22976

Regarding control pins ON1/ON2,  What is typ threshold voltage ?  is it a 50% of VIN rage each input?

Do you have any strict power up/power down sequence VIN,ON,VBIAS Related pins ?

    Yoshimura-san,

    There is no set power sequence for the device but it is preferred that the device is biased to the required voltage first before turning the device ON.

    Please refer to table 7.3 in the datasheet for the V_ih and V_il levels for the control pins. The ON/OFF control is based of these voltages and not a percentage of VIN.
