Power Management and Protection

Increase efficiency and battery autonomy in hybrid and electric vehicles

ST’s new AEC-Q101-qualified 650 V SiC 12- to 40-amp diodes feature a low VF at high temperature (175 °C) – at least 150 mV VF improvement versus 600 V silicon-based/ultrafast diodes – and a high-surge capability (IFSM ). Ideal for on-board battery chargers (OBCs) for hybrid and electric vehicles (HEVs, EVs), they prove superior efficiency as well as robustness. Housed in TO-220AC, DO-247 and TO-247 packages (with PPAP available upon request), their excellent thermal properties help to further improve overall vehicle reliability.


New 650 V SiC MOSFET to complete qualification to AEC-Q101 in early 2017

Currently sampling to lead customers, ST has extended its portfolio of SiC MOSFETs with the introduction of the 650 V, 22 mΩ typ (at 150 °C) SCTW100N65G2AG. The new device will complete the qualification to AEC-Q101 in early 2017 and features the industry’s highest junction-temperature rating of 200°C and shows a very small variation of the on-state resistance even at high temperatures for higher system efficiency. When used in the EV/HEV main inverter, it increases the efficiency by up to 3% compared with an equivalent IGBT solution, translating into longer battery life and a lighter power unit.


Try ST’s newest automotive-grade high-frequency DC-DC regulator with up to 3 A

The STEVAL-ISA160V1 evaluation board is based on the AST1S31HF PWM synchronous step-down regulator, whose very high switching frequency (2.3 MHz) allows miniaturizing the magnetic components (i.e. choke). Operating on a 2.8 to 4.0 V input voltage, it provides a regulated output voltage from as low as 0.8 V up to VIN , meaning that the duty cycle can reach 100% (when VOUT = VIN ) thus optimizing efficiency. A Power Good pin gives precise feedback to the MCU preventing the system from starting before the output voltage is stable. All evaluation board components are automotive grade.


Find best DC-DC solution with ST’s automotive-grade regulator eval boards

Designed for 5 V fixed output, the STEVAL-ISA189V1 evaluation board is based on our A6986F5V synchronous step-down switching regulator that can deliver up to 1.5 A and, with its 100% duty cycle ability to withstand cold crank events and wide input operating voltage range, represents the ideal choice for battery-powered automotive systems. Moreover, a low-noise mode improves the performance of infotainment applications. For a 3.3 V fixed output solution, have a look at our STEVAL-ISA188V1.


Shield onboard equipment with jump-start-compatible ESD protection

The ESDLIN03-1BWY – housed in SOT323-3L – is a single-line ESD protection device designed to protect automotive equipment. AEC-Q101-qualified, it is suited for LIN or USB interfaces and much more as it combines a very-low capacitance (3.5 pF), a 300 MHz bandwidth and a 28.5 V breakdown voltage. Its excellent ESD and EOS capability makes it suitable for harsh environments since it exceeds ISO 10605 level 4, with 30 kV and reaches an IPP of 3.7 A (8/20 µs).
