产品概述

The MAX4172EUA+ is a low cost, precision, high side current sense amplifier in 8 pin µMAX package. High side power line monitoring is especially useful in battery powered systems, since it does not interfere with the battery charger's ground path. Wide bandwidth and ground sensing capability makes IC suitable for closed loop battery charger and general purpose current source applications. The 0V to 32V input common mode range is independent of supply voltage which ensures that current sense feedback remains viable, even when connected to a battery in deep discharge. To provide a high level of flexibility, the MAX4172 functions with an external sense resistor to set the range of load current to be monitored. It has a current output that can be converted to a ground referred voltage with a single resistor, accommodating a wide range of battery voltages and currents. It is used in closed loop battery chargers/current sources, smart-battery packs and energy management systems.
  • Supply voltage range is 3V to 32V
  • Operating temperature range from -40°C to 85°C
  • Ideal for high side monitoring
  • ±0.5% typical full scale accuracy over temperature
  • 800KHz bandwidth [VSENSE = 100mV (1C)]
  • 200KHz bandwidth [VSENSE = 6.25mV (C/16)]
  • Minimizes board space requirements
  • Maximum supply current is 1.6mA
  • Negative input bias current is 50µA (typ) at VRS+ > 2V
  • Input offset voltage is 200mV
