Electronic components meeting quality specifications established by the Automotive Electronics Council (AEC) are suitable for automotive use without additional component-level qualification testing. Most commonly referenced AEC documents include:

• AEC-Q100 - Failure Mechanism Based Stress Test Qualification For Integrated Circuits
• AEC-Q101 - Failure Mechanism Based Stress Test Qualification For Discrete Semiconductors

Automotive Safety Integrity Level (ASIL) is a risk classification scheme defined by the ISO 26262 - Functional Safety for Road Vehicles standard. This is an adaptation of the Safety Integrity Level (SIL) used in IEC 61508 for the automotive industry. ASIL certified devices enable implementation of ASIL traction inverter designs, dramatically reducing development time and cost.

Power Integrations offers a wide range of automotive qualified devices:

InnoSwitch3-AQ Flyback Switcher ICs
The InnoSwitch3-AQ Family of switcher ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and compact size. It's available with 1700 V SiC, 900 V PowiGaN, 750 V silicon or 900 V silicon options.

LinkSwitch-TN2Q High Voltage Offline Switcher ICs
LinkSwitch-TN2 family of ICs provides significant reduction in component count compared to traditional discrete solutions. Designs using the integrated devices are highly reliable without the use of opto isolators.

Qspeed Diodes

Power Integrations is announcing during PCIM Europe its enhanced hardware-software bundle for brushless DC motors (BLDC) with BridgeSwitch-2, a new high-voltage integrated half-bridge (IHB) motor-driver IC family targeting applications up to 1 HP (746 W).

The new ICs, which feature high- and low-side drivers and advanced FREDFETs with integrated lossless current sensing, deliver inverter efficiency of up to 99 percent. The IHB architecture eliminates hot spots, which increases design flexibility and reliability, slashes component count and saves PCB area.

BridgeSwitch-2 is supported by Power Integrations’ MotorXpert software suite, which includes single-phase trapezoidal control and three-phase sensor-less Field Oriented Control (FOC) modules, speeding inverter development.

BridgeSwitch-2 ICs handle operational exceptions in hardware, which permits the use of IEC 60730 Class A safety software, reducing certification time by months. Quiescent BLDC inverters can be ordered into sleep-mode, reducing driver power consumption to less than 10 mW; this leaves more power available under regulated standby power limits to be allocated for loads such as network access and monitoring.

Cristian Ionescu-Catrina, product marketing manager at Power Integrations, said during PCIM Europe: “The low standby consumption of BridgeSwitch-2-based motor drives enables designers to meet new and emerging EU ERP regulations. BridgeSwitch-2 ICs are also far more efficient than IGBT based IPMs across the entire load range.” He continued: “From startup to performance optimization, the GUI-based tool, terminal emulator and MISRA C-compliant code library of MotorXpert greatly simplifies the design process, allowing the motor architecture to be optimized in real-time without repeated firmware updates. BridgeSwitch-2 is microprocessor agnostic, easing its adoption into existing systems – this is important as engineers update designs to meet more stringent standby regulations.”

BridgeSwitch-2 ICs address a power range of 30 to 746 W (1 HP), encompassing a broad range of applications including heat exchanger fans, refrigerator compressors, fluid and circulation pumps, gas boiler combustion fans, washing machine drums and kitchen blenders and mixers. The IHB architecture reduces component count by 50% and PCB space by 30% over discrete designs by eliminating shunt resistors and associated signal conditioning circuits. Shunt losses are also eliminated, improving efficiency. Precise motor control is achieved with the built-in real-time reporting of phase current (IPH) information. Accurate turn-on/off gate drive and a soft-body diode result in a typical EMI profile 10 dB lower than existing drivers, so a smaller EMI filter can be selected.

BridgeSwitch-2 ICs feature built-in DC overvoltage protection and current limits that protect the inverter and the system without relying on system software. The choice of error-flag or comprehensive fault bus reporting supports a range of system requirements. Emerging use-cases like failure prediction are now possible with the high accuracy of the built-in IPH information and comprehensive reporting via the fault bus. BridgeSwitch-2 motor drives use built-in, hardware-based low- and high-side over-current protection to meet IEC 60335-1 Class A requirements. BridgeSwitch-2 also works without an auxiliary power supply, further reducing PCB area and component count.

InnoMux-2 Off-Line Zero Voltage Switching (ZVS) Flyback Switcher IC for Multi-Output Applications:

• InnoMux2-EP - Up to Three CV Outputs or One CV & One CC Output for a Dimmable LED String
• InnoMux2-BL - One CV and up to Four CC Outputs for Dimmable LED Strings in Monitors or Display Panels

Most modern electronic systems rely on multiple internal voltages to operate various functions such as computing, communication and actuation function – typically heat, light, sound or motion of some kind. But losses in each conversion stage are compounded, degrading system performance and generating heat.

The InnoMux-2 IC overcomes this challenge by providing up to three independently regulated voltage outputs or two voltage output and a constant current output from a single stage, achieving a compact and efficient power sub-system with low component count.

The InnoMux-2 family of single-stage, independently regulated multi-output offline power-supply ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently regulated outputs for use in white goods, industrial systems, displays and other applications requiring multiple voltages.

Elimination of separate DC-DC stages slashes component count, reduces PCB footprint and increases efficiency by as much as 10 percentage points compared to traditional two-stage architectures. Efficiency is aided by the ICs’ 750 V PowiGaN gallium-nitride transistors, zero-voltage switching (without an active clamp) and synchronous rectification.

Highlights

• Single-stage power conversion for high efficiency
• Eliminates post-regulators
  • Up to 10% higher efficiency
  • Low component count
  • Less than 50 mW no-load consumption
• Up to three independently regulated outputs
  • Constant voltage and constant current outputs
  • Less than ±1% combined load/line/cross regulation
