LIN system basis chip with
high-side drivers
The 33910G5/BAC is a SMARTMOS 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 which 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.
