PSOC™ 4 HVPA-SPM 1.0 (smart battery pack monitor) PSOC™ 4 HVPA‑SPM 1.0 is a programmable smart battery pack monitor for automotive BMS. It combines a 32‑bit Arm® Cortex®‑M0+ with high‑precision analog front‑end (ΔΣ ADCs, comparators) for accurate current/voltage/temperature sensing. It supports iso‑UART daisy‑chain plus CAN‑FD to reduce host MCU load and enable robust, scalable architectures.
