STMicroelectronics Current Sensing Amplifier Single Channel 5-Pin SOT-23 Package TSC101BILT

STMicroelectronics TSC101BILT is a single channel current sensing amplifier, offered in a compact 5-pin SOT-23 surface mount package. It is engineered to deliver precise current measurement by outputting a voltage proportional to the voltage drop across a low-value resistor in a power rail. This device supports a single power supply voltage range between 4 volts and 24 volts, making it versatile for various electronic circuit designs.

Its high common-mode rejection ratio of 90 dB enhances the accuracy of current sensing by effectively rejecting voltage noise and interference common to both inputs. The low supply current of 300 microamperes ensures energy efficiency, important for portable and sensitive systems.

Physically, the TSC101BILT features a length of 3 mm and a height of 1.3 mm, fitting well into space-constrained applications. It operates reliably over a wide temperature range from -40°C up to 125°C, supporting use in industrial environments with temperature extremes. With a gain bandwidth product of 670 kHz, the amplifier provides responsive signal processing for real-time current monitoring.

The device is tailored for enhancing safety and control in circuits by accurately monitoring current flow through critical power rails. It is particularly suited for measuring currents in power management, battery monitoring, and other instrumentation applications. Note that it does not meet automotive standards, so it is intended for general electronic and industrial use rather than automotive systems.
