LIN system basis chip with DC motor
pre-driver
The 33911G5/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 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 which 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.
Features
• Full-duplex SPI interface at frequencies up to 4.0 MHz
• LIN transceiver capable of up to 100 kbps with wave shaping
• One 50 mA/60 mA high-side and two 150 mA/60 mA low-side protected
switches
• Two high-voltage analog/logic Inputs
• Configurable window watchdog
• 5.0 V low drop regulator with fault detection and low-voltage reset (LVR)
