LM3814/LM3815 Fast Current Gauge IC with Ultra Low Loss Sense Element and PWM Output January 1999 LM3814/LM3815 Fast Current Gauge IC with Ultra Low Loss Sense Element and PWM Output General Description The LM3814/LM3815 Current Gauges provide easy to use precision current measurement with virtually zero insertion loss (typically 0.
004Ω).
The LM3814 is used for high-side sensing and the LM3815 is used for low-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)...
