November 2000
LM3822 Precision Current Gauge IC with Internal Zero Ohm Sense Element and PWM Output
General Description
The LM3822 Current Gauge provides easy to use precision current measurement with virtually zero insertion loss (typically 0.003).
The LM3822 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 50 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. The LM3822 is factory-set in two different current options. The sense range is -1.0A to +1.0A or -2.0A to +2.0A. The sampling interval for this part is 50ms. If faster sam
