LM3824
Precision Current Gauge IC with Internal Zero Ohm
Sense Element and PWM Output
General Description
The LM3824 Current Gauge provides easy to use precision
current measurement with virtually zero insertion loss (typi-
cally 0.003
Ω). The LM3824 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 aver-
aging function. Current is averaged over 6 msec time peri-
ods 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 LM3824 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 6ms. If a more precise mea-
surement is required, please refer to LM3822 datasheet.
