OPTIREG™ | Mid-Range+ SBC family

Overview

Infineon's Mid-Range+ System Basis Chips (SBC) combine power supply with CAN FD and two LIN transceivers.

Mid-Range + SBC offers a high level of integration, performance, and scalability. Up to three low-drop voltage regulators with 5 V or 3.3 V output voltage, one CAN (including partial networking and flexible data-rate), and up to two LIN transceivers complying with the latest automotive standards and OEM requirements.

Key features

  • 5 V/3.3 V linear voltage reg. (250 mA)
  • 5 V linear voltage reg. (100 mA)
  • 5 V/3.3 V/1.8 V Volt. Reg. w/ ext. PNP
  • CAN FD up to 5 Mbps
  • CAN PN FD tolerant ("-3" variants)
  • Up to 2 LIN transceivers
  • Diagnosis & supervision functions
  • Supporting features
  • Low-power fail-safe operating mode
  • Full wake capability
  • SW compatibility w/in SBC family

Integration, performance, and scalability with Mid-Range+ SBCs

The devices include diagnostic and supervision features to support ECU functional safety concepts like under-voltage monitoring, window watchdog with reset, fail-safe operating mode, and fail-safe outputs. There are also available four high-side switches to drive external loads, wake inputs, and general-purpose input outputs (GPIOs) to monitor inputs or activate loads. Mid-Range SBCs offer low-power modes to support applications that are connected permanently to the battery. All devices feature an exposed pad PG-VQFN-48 (7 mm x 7 mm) power package (supporting automatic optical inspection). The entire family is pin–to–pin and software compatible and is designed to withstand the severe conditions of automotive applications.

Multiple benefits including space and energy savings

  • Space saving: 80 percent PCB board space savings by integrating eight chips in one single VQFN package with a 7 x 7 mm² footprint.
  • Energy saving: Offers intelligent power saving modes including stop and sleep mode, and supports energy management enabling very low quiescent current mode.
  • High system reliability: Extensive diagnostics and protections are embedded including limp home functionality.
  • Reduced cost: Minimum number of external components reduce. Savings in BOM cost, part placing and handling, PCB board size, purchasing, and development.
  • Multiple and flexible designs: Compatible hardware and software reduce design costs and effort, enabling usage in various applications.

Excellent software and hardware compatibility

The entire family is pin–to–pin and software compatible. The Mid-Range+ SBC allows scalability in terms of amount of LIN transceivers as well as flexibility for 3 V power supply and CAN partial networking option. It is also software compatible with the Lite, DC-DC, and Multi-CAN Power+ SBC families (TLE94x1 and TLE927x).
