TPIC1021DR Datasheet/PDFThe TPIC1021DR is an advanced, low-power driver and receiver device intended for use in automotive and industrial applications. This product is designed for reliable, high-speed communication over wide range of operating temperature and reducing the electromagnetic interference (EMI) in automotive and industrial environments. The TPIC1021DR can be driven from either an open-collector or an inverting driver, and its design ensures that the output is fast, short-circuitable and fault-tolerant.
Application Field
The TPIC1021DR is very versatile in it\'s applications and is suitable for many applications, such as data transmission, audio/video, automotive and industrial control. The driver/receiver device is designed to operate in a wide variety of operating temperature ranging from -40C° to +85°C. It offers quick and reliable data acquisition and transmission, and it is suited for applications such as instrumentation and diagnostics, engine control, in-vehicle networks and aerospace.
Working Principle
The TPIC1021DR offers an industry-standard, open-collector or inverting driver/receiver circuit for quick and reliable data transmission. The device features a bidirectional, localized bus switch that can dual-route signals between its receiver and drivers. The circuit architecture ensures that the drivers are always active, while the receiver circuit is active only when data is being transmitted. The switch is designed with a low-active level to make it tolerant to fault conditions and ensure minimal power dissipation.
The high-speed switching takes place in the reverse high logic level. In this mode, the voltage at the S pin is usually higher than the voltage at the R pin. The receiver is activated only when the S pin is higher than 5V. This allows the VPIC1021DR to maintain its active state with considerably less power than a conventional transmitter/receiver circuit. In addition, the device supports constant current sourcing, current sensing, inrush current limiting, short-circuiting protection, and provides access to diagnostic information.
The device has optimized design for modernized, high speed communications and allows for a wide range of operating temperature values. It is also geared for use in automotive and industrial applications and offers certification and compliance with EMC standards. The product also offers precision accuracy, wide dynamic range, safety and stability.
