Power management IC for automotive functional safety applications
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.
