OPTIREG™ lite SBC

High integration with Lite SBC technology

The Lite SBCs family offers two variants: Lite LDO SBC with a low-dropout voltage regulator of 150 mA and the Lite DC-DC SBC with a DC-DC buck converter of up to 500 mA. Both variants are available as 5 V or 3.3 V output voltage options for microcontrollers, network transceivers, sensors, and other peripherals’ power supply. 

They feature an auxiliary 5 V integrated low-drop voltage regulator with up to 100 mA. The communication interface incorporates one CAN transceiver with a flexible data-rate performance of up to 5 Mbps according to ISO 11898-2:2016 (including a Partial Networking option). The devices include diagnostic and supervision features, supporting ECU functional safety concepts like under-voltage monitoring, window watchdog with reset, fail-safe operating mode, and fail-safe outputs.

Why use a Lite System Basis Chip?

• Space saving: 80 percent PCB board space savings by integrating eight chips in one single VQFN package with a 7 x 7 mm 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.

Lite SBC family is software and pin-to-pin compatible

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 3.3 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 & TLE927x).

What are the key benefits of a Lite SBC?

Reduced system cost through low component count and small PCB footprint

Effective external load switch control through its integrated charge pump that can drive an external N-FET; Extends battery life with very low quiescent current modes; Enables design flexibility and reduces software design effort by the shared state machine and SPI access within the entire Lite SBC family; Meets major car OEM requirements with excellent EMC and ESD performance; Safely supply off-board loads (e.g., sensors) with short-circuit protected low-drop voltage regulators
