TPL5110: Possible for DRV only after delay?

DANIEL Harvey
Prodigy 10 points

Part Number: TPL5110

Currently the TPL5110 DRV goes low immediately upon power up regardless of of timer or one shot mode.  Is it possible to configure the device to DRV low only after power on and the set delay finishes? 

Ex; Device is powered on, after 5 min delay set by Rext DRV goes low.

    Hi Daniel,

    I am afraid this is not possible, as you can see from below figure, DRV will return to LOW after POR and resistor reading period, this is where the first counting starts. The device is design in this way and there is no way to alternate this characteristic.
