The current-sense amplifier must have a source imped-
ance of less than the value as constrained by the selection
of the ADC_TIME bits in MFR_MODE and the output from
the amplifier must not exceed the maximum input-voltage
limits of the device. The 100I series resistor is required
to protect the device if the current-sense amplifier can be
active when the system manager is powered off.
The VOUT_SCALE_MONITOR command can be used to
properly scale the external sense element and current-
sense amplifier gain so that the READ_VOUT com-
mand reports current instead of voltage. Normally VOUT_
SCALE_MONITOR scales voltage from 0 to 32.767V in
1mV steps. For channels used to measure current instead

of voltage, the VOUT_SCALE_MONITOR command can
be configured to report current from 0A to 32.767A in 1mA

some examples. Note that VOUT_SCALE_MONITOR can-
not exceed a ratio of 1. System designs should avoid RG
combinations with a value greater than 1.
The device uses the exposed pad of the TQFN pack-
age as the common ground (V
The exposed pad must be connected to the local
ground plane.
