February 2005
LM3812/LM3813 Precision Current Gauge IC with Ultra Low Loss Sense Element and PWM Output
General Description
The LM3812/LM3813 Current Gauges provide easy to use precision current measurement with virtually zero insertion loss (typically 0.004).
The LM3812 is used for high-side sensing and the LM3813 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 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 LM3812 and LM3813 are factory-set in two different current options. The sense range is -1A to +1A or -7A to
