6.1.1 Introduction
6.1 System Controller
Table 2.
The exposed die pad at the bottom of the package allows for better heat dissipation from
the SBC via the printed circuit board. The exposed die pad is not connected to any active
part of the IC and can be left floating, or can be connected to GND.
The UJA1079 combines the functionality of a LIN transceiver, a voltage regulator and a
watchdog (UJA1079/xx/WD versions) in a single, dedicated chip. It handles the power-up
and power-down functionality of the ECU and ensures advanced system reliability. The
SBC offers wake-up by bus activity, by cyclic wake-up and by the activation of external
switches. Additionally, it provides a periodic control signal for pulsed testing of wake-up
switches, allowing low-current operation even when the wake-up switches are closed in
Standby mode.
The LIN transceiver is optimized to be highly flexible with regard to bus topologies.
V1, the voltage regulator, is designed to power the ECU's microcontroller, its peripherals
and additional external transceivers. An external PNP transistor can be added to improve
heat distribution. The watchdog is clocked directly by the on-chip oscillator and can be
operated in Window, Timeout and Off modes.
The system controller manages register configuration and controls the internal functions
of the SBC. Detailed device status information is collected and presented to the
microcontroller. The system controller also provides the reset and interrupt signals.
