ST Microelectronics is leading progress toward sensing equipment with lower-cost precision control of functions such as battery monitoring, power management and motor control with its latest generation of high-side current sensing ICs. ST’s TSC1021 single-chip high-side current sense amplifier simplifies the design of accurate measurement circuitry in electronic control units and achieves a lower by leveraging its own high-voltage manufacturing process.
The TSC1021 current-sense amplifier can now target a wide range of applications at a far more competitive price for equipment such as automotive actuators and battery-powered products due to the common-mode operating range of 2.8V to 30V, and the ability to withstand an outstanding range of -32V to +60V on its input pins without damage.
The more focused common-mode voltage range feature of the TSC1021 benefits from high temperature stability, as well as high immunity to electromagnetic interference (EMI) thanks to its built-in filtering. This will safeguard performance in industrial and automotive environments, and allow the application of various types of equipment.
The TSC1021 current-sense amplifier allows use of equipment such as:
- Accurate positioning mechanisms
- Safety systems
- Automotive window control, Electric doors and seats,
- Cooling fans
- Fuel pump applications
- 2.8V to 30V common-mode voltage range
