Description
L5965 is a multiple voltage regulator composed by two battery compatible BUCK pre-
regulators (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.
