Overview

LM3824 Precision Current Gauge IC with Internal Zero Ohm Sense Element and PWM Output July 2000 LM3824 Precision Current Gauge IC with Internal Zero Ohm Sense Element and PWM Output General Description The LM3824 Current Gauge provides easy to use precision current measurement with virtually zero insertion loss (typically 0.
003Ω).
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 di...
