Part Number: BQ35100
What is the proper way to configure the VIN sensing for the battery voltage when the battery voltage is very high (say 300V). It is not clear what the effective input Z would be for the Vin pin (note the BAT pin has 8Mohm / 100kohm specs).
Please suggest a circuit (perhaps a buffer amp is required?) to allow sensing of a ~ 300V battery that does not draw excessive sensing current.
What are the timing requirements for sampling the Vin pin in the cases where Vin sensing would be switched on and off to reduce power draw?
