MAXIM INTEGRATED / ANALOG DEVICES MAX9929FAUA Current Sense Amplifier

The MAX9929FAUA is a high-precision, micropower, uni-/bidirectional current-sense amplifier designed for monitoring load currents in portable and battery-powered systems. It features an input common-mode voltage range from -0.1V to +28V, operating from a 2.5V to 5.5V supply, with a low quiescent current of 20μA. The device offers a fixed voltage gain of 50V/V, with an external resistor setting the full-scale output voltage. Its SIGN output indicates the direction of current flow, enabling accurate detection of charging or discharging states in energy storage applications. Compact in a 6-bump UCSP package, the MAX9929FAUA covers a wide temperature range of -40°C to +125°C for automotive and industrial uses, making it ideal for high-side current sensing with minimal power consumption.
