TPS25942x - About supply current

Hide
Guru 21045 points
Other Parts Discussed in Thread: TPS25940

Hi Team,

 

I understand that the supply current decreases if this device is disabled.

However, our customer would like to decrease this current at enabled.

Because, they would like to maintain the state that internal MOSFTE was turned on.

 

 

I understand that this device does not have something like “Power save mode”.

However, could you please let us know if you have any idea to decrease this current?

 

[conditions]

Vin=4.0V to 8.4V (Battery)

ORing circuit

 

Regards,

Kanemaru

    HI Kanemaru-san,

    Have a look at the TPS25940 this has Device Sleep Mode (DevSleep), which can put the device into a lower Iq state.

    I think this may still be a little high for battery applications, but it is the best we have today.

    Regards,
