BQ24195L: External current sense amplifier on current shunt

Mike Yu

Part Number: BQ24195L

Hi Team,

The customer is asking that is it fine to put a current sense amplifier across the resistor to monitor the charging current? Or is there any other way to get the charging current information? Thank you.

Best regards,

Mike

Mike,

An alternate method for measuring charge current is to either use an oscilloscope with hall effect current probe or place a 1% or better, thermally capable (for example, 0.010 Ω in 1210 or larger footprint) resistor in series between the BAT pin and battery and measure the voltage across that resistor.

Thanks,

Ning.
