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. The after-market alternator may have different or no load dump protection, which could lead to damaging the electronic control unit (ECU). This TI Design provides protection to handle these potential unsuppressed load dump pulses (12 V and 24 V) with hardware control. Class A operation may be attained during unsuppressed load dump pulses.

The TIDA-01255 design is built for isolated CAN communication, which is widely used in automotive environments. In hybrid and electric vehicles (HEV/EVs), a complete high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. The TIDA-01255 design supports applications with a simple isolated transformer driver to transfer power. This TI Design has a low-transmission delay, which reduces the loop delay and supports higher baud rates of the CAN.

This 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. This design solves these problems by using TI’s current shunt monitors and signal conditioners (INA240, PGA400-Q1).
