This work presents a single-chip integrated Smart Driver, especially suited for inductive loads, although it can be used also for capacitive or resistive loads. The proposed smart driver has been realized in a 0.35 µm HVMOS technology. Besides the power MOS device and the relevant gate driving circuitry, the smart driver has integrated self-monitoring/diagnostic capability, it can sustain the large...
This work aims to present an High Voltage High Power and High Frequency CMOS DC-DC converter able to work in both Flyback and Boost configurations, designed for automotive applications. The system, implemented in Austriamicrosystems 0.35um HVCMOS technology, is able to manage input voltages from 2.5V up to 36V and generates a programmable output voltage from 6 to 36V with an output current up to 900mA...
The battery is a fundamental component of electric vehicles, which represent a step forward towards sustainable mobility. Lithium chemistry is now acknowledged as the technology of choice for energy storage in electric vehicles. However, several research points are still open. They include the best choice of the cell materials and the development of electronic circuits and algorithms for a more effective...
State-of-Charge estimation is one of the most important task of Battery Management Systems in hybrid and electric vehicles. Knowing the amount of charge stored in each cell of the vehicle battery pack is indeed crucial for effective battery utilisation that prevents cells from damaging and extends the battery lifetime. This is even more relevant for lithium batteries that are less tolerant to overcharging...
This paper presents an innovative and effective approach to design and test a regulator for an automotive alternator with programmable functionalities. The prototype system consists of two different parts: an integrated circuit (IC) and a FPGA. The IC, implemented in austriamicrosystems HVCMOS 0.35 ??m technology, includes all the high voltage parts and a power switch with very low ON resistance....
This work presents a High-Voltage Low-Power CMOS DC-DC buck regulator for automotive applications. The overall system, including the high and low voltage analog devices, the power MOS and the low voltage digital devices, was realized in the Austriamicrosystems 0.35 HVCMOS technology, resulting in a 6.5 mm2 die. The regulator is able to manage a supply voltage down to 4.5 V and up to 50 V and generates...
