LIN System Basis Chip with DC
Motor Pre-driver
The 33911G5/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 33911 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.
One 50 mA/60 mA high side switch and two 150 mA/160 mA low
side switches with output protection are available. 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 these
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 (V
DD
off, wake-up via LIN, wake-up inputs (L1, L2),
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 33911 is compatible with LIN Protocol Specification 2.0, 2.1, and
SAEJ2602-2.
