产品概述

The MAX4211BEUE+T from Maxim Integrated Products is a low cost, low power high side power and current monitor in 16 pin TSSOP 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 MAX4211 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 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. It is 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.
  • 2.7V to 5.5V power supply voltage range, 4V to 28V input source voltage range
  • Open-drain outputs can be connected to potentials as high as 28V
  • Power sense amplifier gain of 1.000 1/V (VPOUT/(VSENSE x VRS+)), internal reference
  • Maximum POUT gain accuracy of ±1.5% at TA = +25°C (VSENSE = 10mV to 100mV, VRS+ = 25V)
  • 150mV current sense full scale voltage, operating temperature range from -40°C to 85°C
  • IOUT power supply rejection of 80dB, POUT power supply rejection of 70dB at VCC = 2.7V to 5.5V
  • 25V/V current sense amplifier gain
  • Low supply current of 670µA 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
  • Baseband Analog Multipliers; Measurement Instrumentation; Overpower Circuit Breaker; Power-Level Detectors
  • Power-Supply Displays; Short-Circuit Protection; Smart Battery Packs/Chargers; Smart Peripheral Control; VGA Circuits
