The SA47321M is a multi-output power supply management device which integrates a multi-channel power supply for automotive applications. The pre-regulator can support a wide input voltage range of 3V to 40V, and up to 2.5A output current. Fully integrated switching regulators and linear regulators can provide multiple output voltage rails, support low power mode and are available with various wake-up sources.

The SA47321M integrates safety functions, with two configurable fail-interrupt outputs which can meet ISO 26262 ASIL-D level.

The SA47321M is available in a compact QFN7×7-48 package.
