L5953 Description
The L5953 is the integration of one switching regulator, two linear voltage regulators, two low voltage warnings and two high side drivers. It has a stand-by operation mode (low current consumption) where only the stand-by voltage regulator plus the low voltage warnings are active. The other regulators and high side drivers are controlled by the SPI interface.
