LM3812, LM3813
www.ti.com SNOS028D – JUNE 1999 – REVISED APRIL 2013 LM3812/LM3813 Precision Current Gauge IC with Ultra Low Loss Sense Element and
PWM Output
Check for Samples: LM3812, LM3813 FEATURES DESCRIPTION •
• The LM3812/LM3813 Current Gauges provide easy
to use precision current measurement with virtually
zero insertion loss (typically 0.004Ω). The LM3812 is
used for high-side sensing and the LM3813 is used
for low-side sensing. 1 2 •
