Page 11: Current Test Using Lpc4322
Due to the input offset voltage variations in MAX9634, the current measurement circuit is not recommended for measuring currents below 150 A. The QN908x current can be measured by the voltage across a sense resistor in series with the supply. The voltage across a series 4.12-Ω resistor with the target QN908x VCC can be manually measured at JP12 on the PCB. -
