STMicroelectronics TSC101BILT Current Sense Amplifier

The TSC101BILT from STMicroelectronics is a high-precision current sense amplifier designed for applications requiring current monitoring. This device is particularly well-suited for battery management systems, power supply control, and overcurrent protection circuits. By providing a voltage output proportional to the measured current, the TSC101BILT enables systems to perform accurate current monitoring without directly interfacing with the high-current path.

Featuring a wide common-mode input voltage range from 2.8V to 30V, the TSC101BILT is versatile enough to handle a variety of operating conditions. This range allows it to function in both low-voltage and high-voltage systems without the need for additional components to shift the input voltage level. The device is designed with a precision voltage reference and an operational amplifier, enabling it to deliver a precise, low-offset voltage output.

With a gain bandwidth product of 500 kHz, the TSC101BILT is capable of providing high-speed current monitoring, making it an ideal choice for fast-switching power supply applications. The low input offset voltage of 300 µV (max) and the low input bias current of 170 nA (max) ensure that the current sensing is accurate and has minimal impact on the system being monitored.

The TSC101BILT is available in a small SOT23-5 package, which is advantageous for space-constrained applications. Its operating temperature range of -40°C to +125°C allows for reliable operation in harsh environments. The device also features a wide supply voltage range from 2.7V to 5.5V, providing flexibility in terms of power supply design.

In summary, the TSC101BILT current sense amplifier from STMicroelectronics is a high-performance solution for precise current measurement in a variety of electronic systems. Its wide input voltage range, low offset, high bandwidth, and compact package make it a valuable addition to any power management or monitoring application.
