INFINEON INTRODUCES PSOC? 4?HVPA-144K MICROCONTROLLER FOR AUTOMOTIVE BATTERY MANAGEMENT SYSTEMS
With the introduction of the PSoC 4?High Voltage Precision Analog (HVPA)-144K microcontroller, Infineon Technologies AG addresses the automotive battery management sector by integrating high-precision analog and high-voltage subsystems on a single chip.
It provides a fully integrated embedded system for monitoring and managing automotive 12?V lead-acid batteries, which is critical for the 12?V power supply of vehicles' electrical systems. The new microcontroller is ISO26262?compliant, enabling compact and safe intelligent battery sensing and battery management in modern vehicles.
The PSoC 4?HVPA-144K’s dual high-resolution sigma-delta ADCs, together with four digital filtering channels, enable accurate measurement of the battery’s state-of-charge (SoC) and state-of-health (SoH) by measuring key parameters such as voltage, current, and temperature with an accuracy of up to ±0.1?percent. The device features two programmable gain amplifiers (PGAs) with automatic gain control, allowing fully autonomous control of the analog front end without software intervention. The use of shunt-based current sensing for batteries provides a higher accuracy than conventional Hall sensors.
An integrated 12?V LDO (42?V tolerant) allows the device to be supplied directly from the 12?V lead-acid battery without the need for an external power supply. An integrated transceiver allows direct communication with the LIN bus. The product meets the functional safety requirements of ASIL-C according to ISO26262.
The Arm? Cortex?-M0+ MCU on which the PSoC 4?HVPA-144K is based operates at up to 48?MHz with up to 128?KB of code flash, 8?KB of data flash and 8?KB of SRAM, all with ECC. The PSoC 4?HVPA-144K also includes digital peripherals such as four timers/counters/PWMs and a serial communication block that can be configured as an I2C/SPI/UART.
The PSoC 4?HVPA-144K is supported by automotive-quality software. Infineon’s Automotive Peripheral Driver Library (AutoPDL) and Safety Library (SafeTlib) are developed according to the standard automotive software development process. They are both A-SPICE compliant, following the MISRA 2012?AMD1?and CERT C, and ISO26262?compliant.
With the introduction of the PSoC 4?HVPA-144K, Infineon is laying the foundation to expand its PSoC microcontroller portfolio to include Li-ion battery management systems for EVs. The portfolio will soon include several products for monitoring and managing high voltage (400?V and above) and low voltage (12?V/48?V) batteries, further facilitating future EV adoption.

TOSHIBA INTRODUCES A PAIR OF AUTOMOTIVE N-CHANNEL MOSFETS TO EXPAND RANGE
New devices in L-TOGL? package offer excellent thermal performance.
Toshiba Electronics Europe GmbH has launched two automotive N-channel power MOSFET devices to meet the growing demand for 48V batteries and systems within automotive applications including inverters, semiconductor relays, load switches, motor drives and more.
The automotive sector requires power semiconductors that offer high levels of reliability coupled with large drain current (ID) ratings and excellent heat dissipation. This is especially true for devices used within traction inverters, battery management systems and junction boxes electric vehicles (EVs) and integrated starter generators (ISGs).
The new 80V XPQR8308QB and 100V XPQ1R00AQB are based upon Toshiba’s new U-MOS X-H process. This gives low levels of on-resistance (RDS(ON)D values of 350A (XPQR8308QB) and 300A (XPQ1R00AQB) continuously with pulsed values (IDP) of 1050A and 900A respectively.
Supporting these low values, the L-TOGL? package adopts a thick copper (Cu) clip-based leadframe structure that thermally and electrically connects the MOSFET die to the package leads. This reduces the package resistance by approximately 70% and channel-to-case thermal impedance (Zth(ch-c)) by 50% compared with the TO-220SM(W) package. Together, the process and clip reduce losses and heat generation while creating a very thermally efficient solution.
Furthermore, the L-TOGL package uses compliant gull-wing leads which reduce mounting stress and improve the reliability of solder joints. It helps to ensure ECU reliability in automotive applications with harsh temperature conditions. Both devices are AEC-Q101?qualified for automotive applications.
MOSFETs are often connected in parallel to increase current capability – especially in automotive applications. To perform effectively, the MOSFET specifications must be closely matched, so Toshiba offers to ship devices grouped to within 0.4V based upon their gate threshold voltage.
Toshiba now offers four MOSFETs housed in the innovative L-TOGL package, including Toshiba’s two existing 40V products, XPQ1R004PB and XPQR3004PB. Toshiba provides suitable products for automotive applications that increasingly require heavy currents, high power density, and excellent levels of robustness.
In conclusion, the symbiotic relationship between the electronics and automotive industries is propelling the electrification of transportation forward at an unprecedented pace. The manufacturing of key EV components within the electronics sector underscores the vital role technology plays in shaping a cleaner, more sustainable future.
As we continue on this trajectory, collaboration, innovation, and investment will be paramount. By leveraging the expertise of the electronics industry, we can overcome manufacturing challenges, drive down costs, and enhance the performance and reliability of EVs.
With each technological advancement and manufacturing breakthrough, we inch closer to a world where electric mobility is not only the norm but also a catalyst for positive environmental change. Through continued research, development, and adoption of cutting-edge technologies, we can accelerate the transition to electric transportation, paving the way for a greener, more efficient tomorrow.
