650kHz High Side Current Sense Amplifier, SOT-23, 3 Pins
Low power high side current sense amplifier in a 3-pin SOT-23 package. Wide voltage range (2.5V-36V) and low 3µA quiescent current.
The Low Power High Side Current Sense Amplifier is a highly efficient device designed to simplify current monitoring in complex electrical systems. By utilising a high-side configuration, this amplifier eliminates the need to disrupt the ground plane when sensing a load current, which is crucial for maintaining signal integrity and system stability.
This device is line-powered, meaning it does not require a separate supply rail to operate, further streamlining circuit design. It features a wide supply and common-mode voltage range from 2.5V to 36V, along with an exceptionally low quiescent current of just 3µA. These specifications make it particularly suitable for applications where power efficiency is critical.
Built to withstand harsh conditions, the amplifier operates over an extended industrial temperature range from -40°C to 125°C. It offers a gain bandwidth product of 650kHz and is housed in a compact, surface-mount SOT-23 package with 3 pins, making it ideal for space-constrained installations.
Applications
This current sense monitor is versatile and reliable, suitable for a broad range of uses including automotive current measurement, industrial systems operating from 24V rails, battery management, over-current monitoring, and general power management applications.
