Texas Instruments' shunt-based current sensor reference design provides an accuracy of < 0.2% FSR over a temperature range of -40°C to +125°C. Precision current sensing is essential in a number of automotive applications, including battery management systems, motor currents, and others. Generally, nonlinearity, temperature drift, shunt tolerances in these locations can cause poor accuracy results.

Fuses are used in many products to avoid current surges and the damage that overcurrent may cause. The traditional fuses used in the Automotive space are low in accuracy and response time. The TIDA-00795 Automotive Precision eFuse reference design is a replacement to the traditional fuse offering higher accuracy and features not found in traditional fuses.

Texas Instruments' reference design shows how to detect current from the mA-to-KA range using a busbar-type shunt resistor. The increasing demand of high-capacity batteries in electric vehicles (EVs) and hybrid electric vehicles (HEVs) drives the requirement for larger current spans and highly-accurate current sensors. Obtaining a good accuracy over three decades (mA toA, 1A to 100 A, and 100A to 1000A) is quite challenging due to large amounts o...

Precision control of automotive proportional solenoids is necessary to achieve the precise control in an automatic transmission, in electronic fuel injectors, and in several automotive actuator applications. In proportional solenoids, the current flowing through the coil is directly oportional to the magnetic field generated. The designer can estimate armature position by knowing the current that is flowing through the solenoid.

  The main focus of the TIDA-01235 reference design is to provide a high density, low cost, and good accuracy thermocouple analogue front end. The protection strategies involved in the design protect the analogue front end from coupling transients.   

  Automotive battery power supply lines are prone to transients while running the system. Typical protections required are overvoltage, overload, reverse polarity, and jump start. During the life of a car, the alternator may be replaced with a non-OEM part.

Texas Instruments' presentation will focus on the voltage and current monitoring solutions within HEV/EV system – specifically on overcoming the challenges of high voltages and maintaining an isolation barrier. Afterwards, they will discuss specific op amp parameters to consider for monitoring within the on-board charger (OBC), battery management system (BMS), DC/DC converter, and inverter end equipments.

Integrated circuits and reference designs will help you innovate and differentiate your powertrain current sensors subsystem. A high magnitude of current flows through the micro-ohm shunt, which results in a small amount of voltage drop across the shunt. Using current shunt monitors, this voltage is amplified and converted into digital for further signal processing.
