New Infineon PSoC 4 HVPA-144K allow for precise measurement of voltage, current, and temperature with an accuracy of up to ±0.1 percent, which is useful for determining the battery’s state-of-charge (SoC) and state-of-health (SoH).
Infineon Technologies to now tackle the automotive battery management market with its new PSoC 4 High Voltage Precision Analog (HVPA)-144K microcontroller.
Combines high-precision analog and high-voltage subsystems on a single chip. The new PSoC 4 High Voltage Precision Analog (HVPA)-144K microcontroller offers a completely integrated embedded system for controlling and keeping track of automobile 12 V lead-acid batteries, which are essential for the electrical systems of cars that run on a 12 V power source.
The new microprocessor complies with ISO26262, allowing for safe and compact intelligent battery management and sensing in contemporary cars.
Four digital filtering channels and dual high-resolution sigma-delta ADCs in the PSoC 4 HVPA-144K allow for precise measurement of voltage, current, and temperature with an accuracy of up to ±0.1 percent, which is useful for determining the battery’s state-of-charge (SoC) and state-of-health (SoH).
With its two programmable gain amplifiers (PGAs) and automated gain control, the device can operate the analog front end entirely on its own without the need for software. Compared to traditional Hall sensors, shunt-based current detection for batteries offers a better level of precision.
The device may be powered directly from the 12 V lead-acid battery without an extra power source thanks to an inbuilt 12 V LDO (42 V tolerant). The LIN bus can be directly communicated with via an inbuilt transceiver. According to ISO26262, the product satisfies the functional safety standards of ASIL-C.
The PSoC 4 HVPA-144K is based on the Arm® Cortex®-M0+ MCU, which has up to 128 KB of code flash, 8 KB of data flash, and 8 KB of SRAM—all with ECC—and runs at up to 48 MHz.
Digital peripherals including four clocks, counters, and PWMs as well as a serial communication block that may be set up as an I2C, SPI, or UART are also included with the PSoC 4 HVPA-144K.
Automotive-grade software is available for the PSoC 4 HVPA-144K. The AutoPDL and SafeTlib libraries from Infineon are created in compliance with the industry standard for automotive software development. They are both ISO26262 and A-SPICE compliant, according to the MISRA 2012 AMD1 and CERT C.
Infineon is setting the groundwork to grow its line of PSoC microcontrollers to incorporate Li-ion battery management systems for electric vehicles (EVs) with the launch of the PSoC 4 HVPA-144K. In order to further support the adoption of EVs in the future, the range will soon include a number of solutions for monitoring and controlling low voltage (12 V/48 V) and high voltage (400 V and higher) batteries.
Availability
The PSoC 4 HVPA-144K is now available in a compact 32-QFN (6×6 mm²) package with up to 9 GPIOs. For an easy start of development, an evaluation board is also available.
