Product overview
Description
STPM066S is a multiple voltage regulator composed by one battery compatible BUCK pre-regulator, one BOOST, one LDO and a precise voltage reference regulator. All the regulators have internal power switches.
OTP (one time programmable) cells are used for the main device parameters programming (output voltages and currents, switching frequencies) and to configure the power up sequence.
An SPI interface can be used to enable or disable the single voltage regulators, for diagnostic information and to program internal blocks parameters (monitor and power-good thresholds, slew rate, etc.).
The device offers a set of features to support applications that need to fulfill functional safety requirements as defined by automotive safety integrity level (ASIL) A-B-C-D.
