Boost your ECU design in terms of power management capability, flexibility, and consumption
The SPSB081 system basis chips embed LIN and optional CAN-FD physical communication layers and two low-dropout regulators: the first with a fixed rail (5 V or 3.3 V), while the second is a programmable tracker voltage regulator. These power management ICs are complete with diagnostics and protections, as well as four high-side drivers to supply LEDs and sensors.
