描述 Description

L5965 is a multiple voltage regulator composed by two battery compatible BUCK preregulators (one of which is a controller), two BUCK post regulators with internal

compensation, one BOOST, one LDO and a precise voltage reference regulator. All

the regulators, except the BUCK1 pre-regulator, 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

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.
