产品概述

The MAX4081FASA+ is a 76V, high side, current sense amplifier with voltage output in 8 pin NSOIC package. The device allows bidirectional current sensing applications, single output pin continuously monitors the transition from charge to discharge and avoids the need for a separate polarity output. It requires an external reference to set the zero-current output level (VSENSE = 0V). The charging current is represented by an output voltage from VREF to VCC while discharge current is given from VREF to GND. For maximum versatility, the 76V input voltage range applies independently to both supply voltage (VCC) and common-mode input voltage (VRS+). High side current monitoring does not interfere with the ground path of the load being measured, this makes the device particularly useful in wide range of high voltage systems. Device offer a high level of integration resulting in a simple, accurate and compact current sense solution.
  • Supply voltage range is 4.5V to 76V
  • Automotive temperature range from -40°C to 125°C
  • Independent operating supply voltage
  • Gain of current sense amplifier is 5V/V with gain accuracy of ±0.1% at 25°C
  • Bandwidth of amplifier is 150KHz, CMRR is 124dB at VRS+ = 4.5V to 76V
  • Low input offset voltage of 100µV at TA = +25°C, input bias current of 5µA at VCC = VRS+ = 76V
  • High Accuracy and low quiescent current
  • Supply current is 103µA
  • Minimizes required board space
