Automotive IC Design suppliers need assistance on two fronts: (1) Creation of high-fault-coverage IC designs to comply with the ISO 26262 standard during manufacturing testing, and (2) Monitoring real-time design failures in the field when the design is in standby, nonoperational mode.

TI Integrated Resolver Sensor Interface Enables Smaller, Safer and More Accurate Rotary Position Sensing
Resolver-to-digital converter enables up to a 50 percent reduction in board space and a lower bill-of-materials cost in automotive and industrial applications
Texas Instruments (TI) (NASDAQ: TXN) introduced what it said is the industry’s first resolver sensor interface with integrated power supply, exciter amplifier and functional safety features. The new device is capable of simultaneously exciting the resolver sensor coil and calculating the angle and velocity of a rotating motor shaft without the external components required by competitive solutions.
• Industry’s first V2X solution with Integrated 802.11p, 802.11n, Bluetooth and 802.15.4 for V2V, V2I and Intra-Vehicle applications
• Replaces solutions from multiple vendors with a solution that includes chipset, module, IEEE 1609 stack, On-Board Unit (OBU) and Road Side Unit (RSU)
• Significantly reduces the integration time and total cost of development for the car OEMs; enabling the connected car to become a reality
• Ultra-low power solution ideal for non-vehicular applications such as bicycles, helmets and smart phones for rider and pedestrian safety
Designed with an Externally Enabled Diagnostic Function andUser-Programmable Switchpoints
Allegro MicroSystems, LLC announced a new unipolar Hall-effect switch with an externally enabled diagnostic function and user-programmable switchpoints.
Allegro’s A1162 has on-chip electromagnetic coils that are used to implement self-test of the sensor’s entire magnetic and electrical signal chain. It is designed for systems where precise magnet switchpoints and safety, reliability, or both, are critical, such as those designed to meet the requirements of ISO 26262.
In normal operating mode, the A1162 functions as a standard unipolar Hall-effect switch. The device output transistor turns on (output signal switches low) in the presence of sufficient magnetic field (>BOP max). The output transistor of the A1162 switches off (output signal switches high) when the magnetic field is removed (automotive applications include shift selectors (PRNDL), seat belt buckles and brake sensors.
When the diagnostic feature is enabled, the output of the A1162 provides a square wave output which confirms the device is properly sensing the internally generated magnetic field. Therefore, use of the A1162 either eliminates the need for redundant sensors in safety-critical applications or increases robustness in safety-critical applications that might otherwise require redundant sensors (drive-by-wire systems, etc.).
This monolithic IC integrates a voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and short-circuit-protected open-collector output able to sink up to 25 mA. The on-board regulator permits operation with supply voltages of 3.8 to 24 V. It is temperature-stable and stress-resistant, making it especially suited for operation over temperature ranges up to 150ºC (L temperature range). Superior high-temperature performance is made possible through advanced dynamic offset cancellation techniques, which reduce the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.
The A1162 is available in an 8-pin eTSSOP package (Suffix LE) and is priced at $0.49 in quantities of 1,000.

ST’s SiC electronics helps achieve 97% power efficiency in a form factor 10x smaller and lighter than existing solutions
Silicon-carbide (SiC) power electronics from STMicroelectronics has enabled the creation of ZapCharger Portable, said to be the world’s smallest, smartest, and safest electric-car charging station from Zaptec, a start-up company.
The market-first portable electric-car charger with built-in electronic transformer, ZapCharger works with any electric car on any grid. Power-conversion capabilities of ST’s SiC MOSFET devices have enabled Zaptec engineers to design a portable, yet powerful piece of equipment. Ten times smaller and lighter than products with the comparable performance, the 3kg, 45 x 10 x 10cm charger delivers an energy efficiency of 97%.
