STMicroelectronics Debuts Precision Current Sense Amplifiers Suitable for Automotive and Industrial Use
STMicroelectronics Unveils High-Accuracy, Space-Saving Bidirectional Current-Sense Amplifier
STMicroelectronics, a global leader in semiconductor solutions, introduces the TSC2020, a groundbreaking bidirectional current-sense amplifier. This innovative device features 100 V-tolerant inputs and internally fixed gain, delivering high accuracy and space savings by eliminating the need for external components typically used for protection and gain-setting.
STMicroelectronics' TSC2020 current-sense amplifier, with its robust 100 V-compatible inputs and built-in fixed gain, streamlines design and reduces footprint by precluding the need for additional protective and gain-setting external elements. It’s geared towards use in various sectors, including servers, power tools, industrial motor management, and power supplies, and comes with the AEC-Q100 certification for automotive applications such as battery management systems (BMS), motor-driven window lifters, and traction inverters.
The TSC2020 is versatile, capable of both high-side and low-side current measurement, and operates across a broad common-mode voltage spectrum from -4 V to 100 V, accommodating 48 V systems and beyond. Its finely tuned internal circuits maintain input offset voltage at a tight ±150 µV, significantly trimming down the need for large external shunt resistors, thereby cutting down on power loss. The amplifier's prowess in detecting minimal voltage drops sharply curtails measurement inaccuracies. With a common-mode rejection rate of a minimum of 100 dB, the TSC2020 maintains precision even amidst the common-mode voltage shifts found in circumstances like inline motor regulation. The amplifier’s heightened pulse-width modulation (PWM) noise rejection also contributes to its robust performance in motor drives and switching power setups.
