Fast Current Gauge IC with Ultra Low Loss Sense Element and PWM Output

General Description\nThe 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 incorporat No external sense element required\nPWM output indicates the current magnitude and direction\nPWM output can be interfaced with microprocessors\nPrecision∆Σcurrent-sense technique\nLow temperature sensitivity\nInternal filtering rejects false trips\nInternal Power-On-Reset (POR);
