Advance Information
LIN System Basis Chip with High
Side Drivers
The 33910G5/BAC is a Serial Peripheral Interface (SPI) controlled
System Basis Chip (SBC), combining many frequently used functions
in an MCU based system, plus a Local Interconnect Network (LIN)
transceiver. The 33910 has a 5.0 V, 50 mA/60 mA low dropout
regulator with full protection and reporting features. The device
provides full SPI readable diagnostics and a selectable timing
watchdog for detecting errant operation. The LIN Protocol Specification
2.0 and 2.1 compliant LIN transceiver has waveshaping circuitry that
can be disabled for higher data rates.
Two 50 mA/60 mA high side switches with optional pulse-width
modulated (PWM) are implemented to drive small loads. One high
voltage input is available for use in contact monitoring, or as external
wake-up input. This input can be used as high voltage Analog Input.
The voltage on this pin is divided by a selectable ratio and available via
an analog multiplexer.
The 33910 has three main operating modes: Normal (all functions
available), Sleep (V DD off, wake-up via LIN, wake-up inputs (L1), cyclic
sense and forced wake-up), and Stop (V DD on with limited current
capability, wake-up via CS, LIN bus, wake-up inputs, cyclic sense,
forced wake-up and external reset).
The 33910 is compatible with LIN Protocol Specification 2.0, 2.1, and
SAEJ2602-2.
