MAXIM INTEGRATED / ANALOG DEVICES MAX4071ATAT High-Side Current Sense Amplifier
The MAX4071ATA+T from Maxim Integrated is a bidirectional high-side current sense amplifier housed in an 8-pin TQFN package. Designed for monitoring battery charge and discharge currents in portable devices such as notebooks and cell phones, it features a wide input common-mode voltage range of 1.35V to 24V, independent of the supply voltage. This ensures accurate current sensing even in deep discharge conditions. The amplifier operates at a supply voltage of 2.7V to 24V, with a typical supply current of 100µA that reduces to 10µA in shutdown mode. It includes an external current-sense resistor and a gain select pin to choose between 50V/V and 100V/V gain configurations. A single output pin indicates whether the current is charging or discharging, eliminating the need for additional polarity detection circuitry. The device offers a total output error of less than 1.5%, an internal 1.5V reference, and excellent performance metrics such as a CMRR of 120dB, input bias current of 2.4µA, and a PSRR of 120dB. It also provides load regulation of 2mV/mA (0 to 500µA) and 4mV/mA (0 to -100µA) with a bandwidth of 100kHz at a gain of 50V/V, making it ideal for precise current measurement applications.
