... FUNCTIONAL DESCRIPTION INTRODUCTION The MC33889 is an integrated circuit dedicated to automotive applications. It includes the following functions: • One full protected voltage regulator with 200 mA total output current capability. • Driver for external path transistor for V2 regulator function. RECEIVE AND TRANSMIT DATA (RX AND TX) The RX and TX pins (receive data and transmit data pins, respectively) are connected to a microcontroller’ ...

... V. When V falls below 3.0 V typical, the SUP MC33889 detects it and stores the information in the SPI register bit called “BATFAIL”. This detection is available in all operation modes. VDD1 VOLTAGE REGULATOR VDD1 Regulator is a 5.0 V output voltage with total current capability of 200 mA ...
Page 26
FUNCTIONAL DEVICE OPERATION OPERATIONAL MODES FUNCTIONAL DEVICE OPERATION INTRODUCTION The device has four modes of operation, normal, stand-by, sleep and stop modes. All modes are controlled by the SPI. An additional temporary mode called “normal request mode” is automatically accessed ...
Page 27
NORMAL REQUEST MODE This is a temporary mode automatically accessed by the device after a wake-up event from sleep or stop mode, or after device power up. In this mode, the VDD1 regulator is ON off, and the ...

... TXD Tx driver CAN mode control SPI Figure 12. Simplified Block Diagram of the CAN Transceiver of the MC33889 General description CAN driver: The CANH driver is a “high side” switch to the V2 voltage (5V). The CANL driver is a “low side” switch to gnd.The turn on and turn off time is controlled in order to control the slew rate, and the CANH and CANL driver have a current limitation as well as an over temperature shutdown ...
Page 31
... The CAN has 3 operation modes: TxRx (Transmit- Receive), Receive Only, and Term-VBAT (Terminated to VBAT). The mode is selected by the SPI. As soon as the MC33889 mode is sleep or stop (selected via MCR register), the CAN interface automatically enters Tem-Vbat mode mode: In this mode, the CAN drivers and receivers are enabled, and the device is able to send and receive messages ...

... OFF CANL driver is ON. RTL termination active CANL driver is OFF. RTL termination switched OFF MC33889 will receive information on one wire only and the consequences are as follows: when the bus is set in dominant: - The differential receiver will toggle - Only one of the single ended receivers CANH or of CANL ...

... MC33889D in Normal mode MC33889D in Normal mode, Standby mode or in stop mode T : duration of the CAN wake up filter, typ 16µs. The MC33889D Rx dominant low level duration is the difference WAKE between the duration of the bus minus the Twake, as illustrated below (Trx_dom = Tbus_dom - Twake) Example: A dominant duration at the bus level of 5 bits of 8us each results in a 40us bus dominant. This results in a 24µ ...
