I use electronic load to replace Motor,phase Voltage UA via a electronic load to UB,but LMP8481 Vout unable to display negative current。
Iout=2A, RSP to RSN is 10mV,Vout=2.5V+2A*5mΩ*20=2.5V+0.2V=2.7V,it’s true!
Iout=-2A,RSP to RSN is -10mV…
Part Number: BQ25895M As described in the title, when I unplug the DC will switch to battery power, but at this time about a second to maintain the shutdown. At present, the cause is not found. Please review our schematic diagram and help analyze the…
