Temperature stable measurement IC for power management and motor control applications
May 31, 2011 // Christoph Hammerschmidt
STMicroelectronics has announced a high-side current-sense amplifier which enhances precision measurement for price-sensitive applications in battery monitoring, power management and motor control. The TSC1021 simplifies the design of accurate measurement circuitry in electronic control unit, the vendor claims.
ST said it achieves a lower cost than existing devices by leveraging its own high-voltage manufacturing process. The TSC1021 provides a common-mode operating range of 2.8V to 30V and the device can withstand an outstanding range of -32V to +60V on its input pins without damage, enabling the device to target a variety of applications at a far more competitive price for equipment such as automotive actuators and battery-powered products.
In addition to its more focused common-mode voltage range, the TSC1021 benefits from high temperature stability, as well as high immunity to electromagnetic interference (EMI) thanks to its built-in filtering. These features will safeguard performance in industrial and automotive environments, and permit use in equipment such as accurate positioning mechanisms and safety systems including use in automotive such as window control, electric doors and seats, cooling fan and fuel pump applications.
Major features of the TSC1021 include -32V to +60V surviving range under reversed battery and load-dump conditions, output voltage drift of 100 ppm/°C maximum on full temperature range, input offset drift 8uV/°C maximum on full temperature range, and an overall current consumption below 300uA.
The device is qualified for automotive usage according to AEC-Q100. Operating temperature range is -40°C to 125°C. The chip is in production now in the TSSOP-8 package, priced at $0.68 in quantities of 1000. Alternative pricing options are also available for larger orders.
