Product Overview

The MAX4210AEUA+ is a low cost, low power high side power and current monitor in 8 pin µMAX package. This real time power and current monitor device provides an analogue output voltage proportional to power consumed by load by multiplying load current and source voltage. The MAX4210 measures load current by using a high side current sense amplifier which makes this device for use in battery powered systems by not interfering with ground path of load. The device is a small, simple 6 pin power monitor intended for limited board space applications. It integrates an internal 25:1 resistor divider network to reduce component count. The MAX4210 is typically used in overpower circuit breakers, smart battery packs/chargers, smart peripheral control, short circuit protection, power supply displays measurement, instrumentation, baseband analogue multipliers, VGA circuits and power level detectors.
  • Supply voltage range from 2.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Power sense amplifier gain of 0.667V/V (VPOUT/(VSENSE x VRS+))
  • Maximum POUT gain accuracy of ±1.5% at TA = +25°C (VSENSE = 10mV to 100mV, VRS+ = 25V)
  • 150mV current sense full scale voltage
  • IOUT power supply rejection of 80dB & POUT power supply rejection of 70dB at VCC = 2.7V to 5.5V
  • Input source voltage range from +4V to +28V
  • Low supply current of 380µA at VCC = +5.5V TA = +25°C
  • IOUT -3dB bandwidth of 220KHz and POUT -3dB bandwidth of 250KHz
  • Input bias current of 14µA at VSENSE = 0mV
