The STMicroelectronics L5965 seven-output automotive power-management IC (PMIC) enables more compact and reliable electronic control units for automotive-vision systems and other in-vehicle applications, leveraging direct operation from battery voltage with register-programmable output voltages and sequencing and integrated functional-safety mechanisms.
With seven regulated outputs, a single L5965 can power an entire camera- or radar-based driver-assistance system including the sensors, memory ICs, processor, and CAN interface circuitry. One-time programmable (OTP) cells for setting the output voltages and sequencing give flexibility to configure the PMIC for a wide variety of Advanced Driver Assistance Systems and other in-car applications.
The L5965’s ability to operate directly from the vehicle battery allows its use without a pre-regulator. Its register-programmable outputs also eliminate voltage-setting resistors, and the on-chip regulators can be used without external compensation circuitry (more info).
