In today’s modern vehicles, features such as seat heating, air conditioning, navigation, infotainment, and driving safety systems have evolved to enhance comfort and the overall driving experience. These systems are powered by complex electronic networks that make cars more intelligent and efficient. It's hard to imagine a time just over a century ago when gasoline-powered cars had no electronic components at all. At the turn of the 20th century, cars featured crank handles, acetylene gas for headlights, and bells to signal pedestrians. Today, cars are essentially advanced digital tools, with most mechanical systems replaced by electronic ones. As the automotive industry moves toward electric and hybrid vehicles, the reliance on gasoline is decreasing, pushing the industry further into digital transformation.
As more mechanical systems are replaced by electronic ones, managing power consumption becomes increasingly crucial. Accurate monitoring of energy use in electric vehicles helps drivers feel more confident about their range. For fully electric vehicles, concerns about battery life and charging stations are common. Hybrid models offer some relief with backup gasoline engines, but electric vehicles still rely on limited and time-consuming charging infrastructure. Therefore, continuous and precise monitoring of each electronic subsystem is essential. This data can help drivers conserve power and extend their travel distance. Disconnecting idle modules from the power bus also contributes to energy savings. Monitoring current and power usage can detect long-term anomalies, predict potential failures, and alert users to necessary maintenance, improving vehicle reliability and reducing downtime.
To monitor power consumption, it's necessary to measure both voltage and current. Voltage can be measured directly using an analog-to-digital converter (ADC), while current is typically sensed using a resistor placed in the power path. The voltage drop across this resistor is then converted into a proportional signal for the ADC. To ensure accuracy, the amplifier used must have a low offset voltage, typically less than 100μV. A microcontroller or processor then multiplies the voltage and current readings to calculate power. Energy consumption is tracked by accumulating these power measurements over time.
For power switching, automotive circuits often use solid-state switches like N-channel or P-channel MOSFETs instead of traditional relays. This allows for a compact PCB design and easier assembly. P-channel MOSFETs are turned on by pulling the gate low, while N-channel MOSFETs require a higher gate voltage, often achieved with a charge pump. Figure 2 illustrates a typical power switch circuit using an N-channel MOSFET.
Power buses also need protection against short circuits and overloads. An integrated solution combining switching, protection, and monitoring is ideal for space-efficient designs. The LTC4282 is a hot-swappable controller and circuit breaker that provides power telemetry and EEPROM storage. It ensures safe power-on and power-off operations, with accurate monitoring of voltage, current, and power through an I2C/SMBus interface.
The LTC4282 offers a dual current path configuration, allowing two parallel current-limited paths for high-current applications. This reduces the stress on individual MOSFETs, lowers costs, and improves system reliability. The device also supports hierarchical start configurations, optimizing performance during startup and normal operation.
In conclusion, the past two decades have seen a dramatic increase in the use of electronic systems in vehicles, driven by functions like power steering, ABS brakes, convenience features, and enhanced safety. As cars become more connected and autonomous, the demand for efficient power management will only grow. Tools like the LTC4282 help reduce the complexity of power monitoring, improve battery efficiency, and support the development of high-power, high-reliability automotive systems. With its innovative design, the LTC4282 is a key enabler in the evolution of modern electric vehicles.
