Denso BCD-on-SOI Toyota Prius Battery Control Module (2023) PMIC Essentials
Share This Post
Analyzing the Denso SV061 power management integrated circuit (PMIC) from the Toyota Prius Mk5 battery control unit (BCU), it reveals collaborative efforts between Denso and Toyota to advance hybrid technology. The SV061, measuring 16.1 mm × 16.0 mm × 2.7 mm, houses a single silicon die labelled "MZ6882", suggesting utilization of a 0.18 µm silicon-on-insulator (SOI) bipolar-CMOS-DMOS (BCD) process. Compared to its predecessor, the MZ567 PMIC die, the MZ6882 die demonstrates enhancements such as an advanced process generation node, reduced DTI width and SOI thickness.
