FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 33912 was designed and developed as a highly
integrated and cost-effective solution for automotive and
industrial applications. For automotive body electronics, the
33912 is well suited to perform relay control in applications
such as a window lift, sunroof, etc. via the LIN bus.
Power switches are provided on the device configured as
high side and low side outputs. Other ports are also provided,
which include a current and voltage sense port, a Hall Sensor
port supply, and four wake-up capable pins. An internal
voltage regulator provides power to a MCU device.
Also included in this device is a LIN physical layer, which
communicates using a single wire. This enables this device
to be compatible with 3-wire bus systems, where one wire is
used for communication, one for battery, and one for ground.
FUNCTIONAL PIN DESCRIPTION
for a graphic representation of the various pins referred to in
the following paragraphs. Also, see the pin diagram on
RECEIVER OUTPUT PIN (RXD)
The RXD pin is a digital output. It is the receiver output of the
LIN interface and reports the state of the bus voltage: RXD
Low when LIN bus is dominant, RXD High when LIN bus is
recessive.
TRANSMITTER INPUT PIN (TXD)
The TXD pin is a digital input. It is the transmitter input of the
LIN interface and controls the state of the bus output
(dominant when TXD is Low, recessive when TXD is High).
This pin has an internal pull-up to force recessive state in
MASTER IN SLAVE OUT PIN (MISO)
The MISO pin sends data to an SPI-enabled MCU. It is a
digital tri-state output used to shift serial data to the
microcontroller. Data on this output pin changes on the
positive edge of the SCLK. When CS is High, this pin will
remain in the high-impedance state.
CHIP SELECT PIN (CS)
CS is an active low digital input. It must remain low during a
valid SPI communication and allow for several devices to be
connected in the same SPI bus without contention. A rising
edge on CS signals the end of the transmission and the
moment the data shifted in is latched. A valid transmission
must consist of 8 bits only.
While in STOP Mode, a low-to-high level transition on this pin
will generate a wake-up condition for the 33912.
case the input is left floating.
ANALOG MULTIPLEXER PIN (ADOUT0)
LIN BUS PIN (LIN)
The LIN pin represents the single-wire bus transmitter and
receiver. It is suited for automotive bus systems and is
compliant to the LIN bus specification 2.0, 2.1, and SAE
J2602-2.
The LIN interface is only active during Normal Mode. See
SERIAL DATA CLOCK PIN (SCLK)
The SCLK pin is the SPI clock input. MISO data changes on
the positive transition of the SCLK. MOSI is sampled on the
negative edge of the SCLK.
MASTER OUT SLAVE IN PIN (MOSI)
The MOSI digital pin receives SPI data from the MCU. This
data input is sampled on the negative edge of SCLK.
The ADOUT0 pin can be configured via the SPI to allow the
MCU A/D converter to read the several inputs of the Analog
Multiplexer, including the VSENSE, L1, L2, L3, L4 input
voltages, and the internal junction temperature.
CURRENT SENSE AMPLIFIER PIN (ADOUT1)
The ADOUT1 pin is an analog interface to the MCU A/D
converter. It allows the MCU to read the output of the current
sense amplifier.
PWM INPUT CONTROL PIN (PWMIN)
This digital input can control the high sides and low sides
drivers in Normal Request and Normal Mode.
To enable PWM control, the MCU must perform a write
operation to the High Side Control Register (HSCR) or the
Low Side Control Register (LSCR).
This pin has an internal 20 ? A current pull-up.
