L5965 Multiple Power Management STMicroelectronics L5965 Multiple Power Management includes two battery-compatible buck pre-regulators, two buck post-regulators, one boost, one LDO and a precise voltage reference regulator. The L5965 Multiple Power Management utilises OTP (one-time-programmable) cells that are used for main device parameters and power-up phase programming. The L5965 provides an SPI interface that can be used for diagnostic information and to program internal block parameters. The L5965 Multiple Power Management offers a set of features to support applications that need to fulfil functional safety requirements as defined by Automotive Safety Integrity Level (ASIL) A-B-C-D.
