33911
The 33911 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 33911 has a 5.0V - 60mA 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 compliant LIN
transceiver, has waveshaping circuitry that can be disabled for higher
data rates.
SYSTEM BASIS CHIP WITH LIN
2ND GENERATION
One 60mA high side switch and two 160mA low side switches with
www.DataSheeot4uUtp.cuotmprotection are available for driving resistive and inductive loads.
All outputs can be pulse-width modulated (PWM). Two high-voltage
inputs are available for use in contact monitoring, or as external wake-
up inputs. These inputs can be used as high-voltage analog Inputs.
The voltage on theses pins is divided by a selectable ratio and
available via an analog multiplexer.
The 33911 has three main operating modes: Normal (all functions
available), Sleep (VDD off, wake-up via LIN, wake-up inputs (L1,L2),
cyclic sense, and forced wake-up), and Stop (VDD on with limited
current capability, wake-up via CS, LIN bus, wake-up inputs, cyclic
sense, forced wake-up, and external reset).
The 33911 is compatible with LIN Protocol Specification 2.0.
