Achieving automotive electromechanical integration ST innovative automotive electronic control scheme

Cars may be the most sophisticated electronic devices that users must operate. Due to its increasing complexity, it is necessary to continuously improve the comfort and convenience of drivers and passengers. These functions involve systems such as roof and door zone control systems, HVAC systems, wiper and seat control systems, and lighting control systems. Here are just a few examples. In this area, ST is a leader in an impressive series of mechatronics "mechatronics" platforms that currently have the characteristics of the automotive industry. ST's system-on-chip (SoC) technology enables sophisticated automotive innovations. It uses highly integrated microelectronics as a mechatronics solution, like a mirrored door application system or a single-chip system integrated circuit.

Auxiliary module solution

The universal auxiliary power supply uses a flyback architecture. However, when the power is very low, a buck architecture is required. Generally, such power supplies are low-power solutions with very low cost and low standby power consumption. The following circuit diagram allows you to flexibly choose recommended products.

ST car alarm products

The theft of cars and the theft of personal items continue to rise, resulting in increasing insurance premiums and property losses. In response to this deteriorating trend, auto manufacturers have launched various products with anti-theft functions, including but not limited to car alarms, intrusion and peripheral sensing, key anti-theft locks, and GPS vehicle position tracking systems. From bridges, low-side and high-side drivers to low-cost, high-performance microcontrollers and a wealth of standard products, ST has a large number of solutions for customers to choose from. The following block diagram illustrates ST products used in car alarms.

Central junction box products

Modern body control modules require highly stable electronic components to ensure safety and controllability under various conditions. The most advanced system can drive a variety of loads: from car lights (incandescent lamps, HID, Xenon) with various advanced diagnostic functions (bulb loss detection, overload, etc.), drive functions (PWM, DC) until replacing existing electromechanical relays Motor. ST has a variety of solutions to choose from, including bridges, high / low-side drivers, advanced regulators, low-cost high-performance microcontrollers, and a wealth of standard products, no matter where the control module is installed on the car ( (Cab, rear, under the hood). The following circuit diagram shows the ST products used in the junction box system.
