The Lite SBC family (TLE94x1) is available as 5V or 3.3V output voltage version for

microcontrollers

, network transceivers, sensors and other peripherals’ power supply.

The Lite LDO SBCs feature a low-dropout voltage regulator with an output current of

150mA as well as an auxiliary 5V low-dropout voltage regulator with 100mA of output

current. The communication interface incorporates one CAN transceiver with Flexible

Data-Rate performance up to 5Mbit/s according to ISO 11898-2:2016 (including

Partial Networking option). It complies with the latest automotive standards and OEM

requirements. All devices feature a PG-TSDSO-24 (8.65mm x 6mm). The entire Lite

SBC family (TLE94x1) is hardware compatible, and is also software compatible with

TLE926x & TLE927x.

Key benefits

› Reduced system cost through low component count and small PCB footprint

› 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 shared state

machine and SPI access within the entire Lite SBC family

› Meets major car OEM requirements with excellent EMC and ESD performance
