The MAX4210/MAX4211 low-cost, low-power, high-side
power/current monitors provide an analog output volt-
age proportional to the power consumed by a load by
multiplying load current and source voltage. The
MAX4210/MAX4211 measure load current by using a
high-side current-sense amplifier, making them espe-
cially useful in battery-powered systems by not interfer-
ing with the ground path of the load.
The MAX4210 is a small, simple 6-pin power monitor
intended for limited board space applications. The
MAX4210A/B/C integrate an internal 25:1 resistor-divider
network to reduce component count. The MAX4210D/E/F
use an external resistor-divider network for greater design
flexibility.
The MAX4211 is a full-featured current and power mon-
itor. The device combines a high-side current-sense
amplifier, 1.21V bandgap reference, and two compara-
tors with open-drain outputs to make detector circuits
for overpower, overcurrent, and/or overvoltage condi-
tions. The open-drain outputs can be connected to
potentials as high as 28V, suitable for driving high-side
switches for circuit-breaker applications.
Both the MAX4210/MAX4211 feature three different cur-
rent-sense amplifier gain options: 16.67V/V, 25.00V/V, and
40.96V/V. The MAX4210 is available in 3mm x 3mm, 6-pin
TDFN and 8-pin µMAX
available in 4mm x 4mm, 16-pin thin QFN and 16-pin
TSSOP packages. Both parts are specified for the -40°C
to +85°C extended operating temperature range.
