Multi-channel power management IC for OBC, MCU, and ECU safety applications

power management IC for automotive vision and radar systems

Power management IC for automotive functional safety applications

Requiring only a single chip for each MCU, the STPM066S reduces BOM count, optimizes space and speeds up development.  This automotive-qualified PMIC integrates one battery-connected buck pre-regulator, one boost post-regulator, an LDO and a VREF regulator. The STPM066S simplifies designs thanks to its OTP memory that lets you program key parameters and configure the power-up sequence.
