Overview

The MAX4210/MAX4211 low-cost, low-power, high-side power/current monitors provide an analog output voltage 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 especially useful in battery-powered systems by not interfering with the ground path of the load. The MAX4210EEUA 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 monitor. The device combines a high-side current-sense amplifier, 1.21V bandgap reference, and two comparators with open-drain outputs to make detector circuits for overpower, overcurrent, and/or overvoltage conditions. 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 current- sense amplifier gain options: 16.67V/V, 25.00V/V, and 40.96V/V. The MAX4210EEUA is available in 3mm x 3mm, 6-pin TDFN and 8-pin μMAX packages and the MAX4211 is 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.
