The LM3824 Current Gauge provides easy to use precisioncurrent measurement with virtually zero inserTIon loss (typically0.003W). The LM3824 is used for high-side sensing.A Delta Sigma analog to digital converter is incorporated toprecisely measure the current and to provide a current averagingfuncTIon. Current is averaged over 6 msec TIme periodsin order to provide immunity to current spikes. The ICshave a pulse-width modulated (PWM) output which indicatesthe current magnitude and direcTIon. The shutdown pin canbe used to inhibit false triggering during start-up, or to entera low quiescent current mode.
