BQ34Z100-R2: VEN and control

Saravanakumar Irulappan

Part Number: BQ34Z100-R2

Tool/software:

Hi,

From datasheet it is clear that VEN is used to enable and disable the voltage translation circuit. How to control this pin? Is this through I2C? If yes then please specify the register bit.

Regards,

Saravana

Hello Saravana,

VEN enable is not control through the user and is internally controlled by the IC.

Thank you,
Alan

Hi Alan,

Thanks for your input. If it is internally controlled, then for which event/basis VEN will be ON and at what frequency this is set ON and OFF.

Regards,

Saravana

Hello Saravanakumar,

Please reference this e2e below where it states that "(VEN) pulse to 2.5V every 1 second when the voltage measurements are taken. It also sinks current when pulled to 2.5V externally"

Thank you,
Alan
