The SA59131 Series are fixed-gain, high-speed, high precision, high-side or low-side bidirectional current-sense amplifiers with a voltage output. It operates over a wide common-mode voltage range of –4V to 80V, independent of the supply voltage. The negative common-mode voltage allows the device to operate below ground. Enhanced PWM rejection makes the SA59131 Series suitable for current sensing and overcurrent protection in switching systems with large common-mode voltage transients (high ΔV/Δt) at the device's inputs, such as HEV/EV's DC/DC converters, motor controls, and battery management systems.

The SA59131 Series utilize zero-drift architecture. Its low input offset voltage (VOS) enables precise measurement of low-voltage drops. The devices operate from a single 2.7V to 5.5V power supply and draw 1.8mA (typ.) quiescent current. 

The devices are available in SOP8 package and are specified over operating temperature range of -40°C to 125°C. The devices are AEC−Q100 Grade 1 Qualified.
