The LM3824 Current Gauge provides easy to use precision
current measurement with virtually zero insertion loss (typically
0.003W). The LM3824 is used for high-side sensing.
A Delta Sigma analog to digital converter is incorporated to
precisely measure the current and to provide a current averaging
function. Current is averaged over 6 msec time periods
in order to provide immunity to current spikes. The ICs
have a pulse-width modulated (PWM) output which indicates
the current magnitude and direction. The shutdown pin can
be used to inhibit false triggering during start-up, or to enter
a low quiescent current mode.
