MAXIM INTEGRATED / ANALOG DEVICES MAX4173FESA High-Side Current Sense Amplifier
The MAX4173FESA+ is an ultra-compact, high-side current sense amplifier in an 8-pin NSOIC package. It provides a voltage output that eliminates the need for gain-setting resistors, making it ideal for applications requiring precise current monitoring. This high-precision amplifier features a wide input common-mode range, enabling reliable feedback even when connected to a deeply discharged battery. With a bandwidth of 1.4 MHz, it is suitable for use in battery charger control loops and power management systems. The device offers a full-scale current reading, simplifying design and integration. It is used in applications such as power management, current monitoring on boards, PA bias control, and precision current sourcing. It operates from a supply voltage of 3V to 28V, with a temperature range of -40°C to 85°C. Designed for high accuracy, it has a gain of 50 V/V with ±0.5% full-scale accuracy, a common-mode rejection ratio of 90 dB, and a power supply rejection of 91 dB. The input bias current is 100 µA at VRS ≤ +2V, and it consumes approximately 420 µA of power.
