LIN System Basis Chip with High
Side Drivers
33910
The 33910 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 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.
SYSTEM BASIS CHIP WITH LIN
2^ND GENERATION
Two 50 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).
