MAXIM INTEGRATED / ANALOG DEVICES MAX4070AUA Bidirectional Current Sense Amplifier
The MAX4070AUA+ is a precision bidirectional current sense amplifier housed in an 8-pin µMAX package. It offers an input common-mode voltage range from 1.35V to 24V, independent of the supply voltage, ensuring accurate current sensing even when connected to a deeply discharged battery. The device features a low supply current of 100µA, reducing to approximately 10µA in shutdown mode. It includes an external current-sense resistor and a gain select pin (GSEL) to choose between 50V/V and 100V/V gain settings—drive GSEL low for 50V/V, high for 100V/V. A single output monitors the transition between charging and discharging, eliminating the need for a separate polarity signal. It is ideal for battery charge/discharge monitoring, power management, motor control, and instrumentation applications.
