L5965：Multiple power management for automotive vision and radar systems

The L5965 is a multiple voltage regulator including two battery compatible BUCK pre-regulators, two BUCK post regulators, one BOOST, one LDO and a precise voltage reference regulator.

OTP (One Time Programmable) cells are used for main device parameters and power up phase programming.

An SPI interface can be used for diagnostic information and to program internal blocks parameters.

Voltage supervisors, programmable watchdog, voltage reference and additional safety management functionalities make the product able to supply a microcontroller and fulfill the requirements for automotive cameras and radars.
