Power rail switch (PRS)

在新型电动汽车中,由两种不同的电源(如电池和DC-DC转换器)为车辆负载供电。因此,系统采用两条并行的电源轨来实现从电源到负载的配电。 这两个系统并未完全隔离。电源轨开关 (PRS) 是一种双向器件,能在其中一个电源轨或电源发生故障时,将负载连接到备用电源轨或电源。PRS负责控制和管理连接到配电单元 (PDU) 和区域控制单元 (ZCU) 系统的并行电源轨。

STi²Fuse, smart switches for wire harness protection

STi²Fuse is a new family of intelligent fuses designed to replace standard melting fuses in automotive power distribution systems.

These devices enable savings on components and production costs while extending EV range and reducing the vehicle's carbon footprint. Their monitoring, control, and digital interface capabilities help automotive systems comply with ISO 26262 and related Safety Integrity Levels (SIL).

Stellar 32-bit automotive MCUs

The Stellar platform consists of multiple series of automotive microcontrollers built around a versatile Arm®-based architecture. The Stellar P and Stellar G series are designed to support real-time virtualization of multi-ASIL ECUs while the Stellar E series addresses the needs for electrification.

All series boast an extensive array of I/Os and peripherals, making them suitable for modern car ECU solutions. The Stellar P & G product lines include xMemory, build on ST PCM technology, providing over twice the memory density compared to other eNVM technologies. Stellar with xMemory offers more headroom for current and future application needs.

Automotive STripFET F8

The advanced STripFET F8 technology ensures lowers output capacitance, which helps reduce voltage spikes across the drain source and decrease energy losses during charge-discharge cycles. This new low-voltage MOSFET series features an enhanced body-drain diode that improves softness during switching to further reduce electromagnetic interference. These performance improvements help designers meet EMC requirements and simplify compliance verification processes associated with various low-voltage automotive applications.
