TPS22919: Rqod selection

Takashi Onawa

Part Number: TPS22919

Hi Team,

Are there any restrictions on the value of the Rqod? Please let me know the recommended range if there is.
There is no specific requirement for fall time in my customer's system.

Hi Onawa-san,

There is no max resistance that can be used on QOD. The choice here depends on the discharge/off time for the system.

It is possible to directly connect the VOUT pin to QOD but if there is not specific off time requirement, I would use a 1Kohm resistance from VOUT to QOD to reduce the discharge current seen. On the EVM, we use no QOD, 1k QOD and 2k QOD for this device (wit selection jumpers).
