General Description
The MAX9928/MAX9929 low-cost, uni-/bidirectional,
high-side, current-sense amplifiers are ideal for moni-
toring battery charge and discharge currents in note-
books, cell phones, and other portable equipment.
These devices feature a wide -0.1V to +28V input com-
mon-mode voltage range, low 20A supply current with
VOS less than 0.4mV, and a gain accuracy better than
1.0%. The input common-mode range is independent
of the supply voltage, ensuring that the current-sense
information remains accurate even when the measure-
ment rail is shorted to ground.
The MAX9928F features a current output with a transcon-
ductance ratio of 5A/mV. An external resistor converts
the output current to a voltage, allowing adjustable gain
so that the input sense voltage can be matched to the
maximum ADC input swing. The MAX9929F has a voltage
output and integrates a 10k
Ω output resistor for a fixed
voltage gain of 50V/V.
A digital SIGN output indicates direction of current flow,
so the user can utilize the full ADC input range for mea-
suring both charging and discharging currents.
The MAX9928/MAX9929 are fully specified over the -40°C
to +125°C automotive temperature range, and available
in 6-bump UCSP (1mm x 1.5mm) and 8-pin MAX
packages. The UCSP package is bump-to-bump com-
patible with the MAX4372_EBT.
