FUNCTIONAL DESCRIPTION
INTRODUCTION
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.
Reset, programmable watchdog function
Four operational modes
Wake-up capabilities: Forced wake-up, cyclic sense and wake-up inputs, CAN and the SPI
Can low speed fault tolerant physical interface.
FUNCTIONAL PIN DESCRIPTION
RECEIVE AND TRANSMIT DATA (RX AND TX)
The RX and TX pins (receive data and transmit data pins, respectively) are connected to a microcontroller’s CAN protocol
handler. TX is an input and controls the CANH and CANL line state (dominant when TX is LOW, recessive when TX is HIGH).
RX is an output and reports the bus state (RX LOW when CAN bus is dominant, HIGH when CAN bus is recessive).
VOLTAGE REGULATOR ONE (VDD1)
The VDD1 pin is the output pin of the 5.0 V internal regulator. It can deliver up to 200 mA. This output is protected against
overcurrent and overtemperature. It includes an overtemperature pre-warning flag, which is set when the internal regulator
temperature exceeds 130 °C typical. When the temperature exceeds the overtemperature shutdown (170 °C typical), the
regulator is turned off. VDD1 includes an undervoltage reset circuitry, which sets the RST pin LOW when VDD is below the
undervoltage reset threshold.
RESET (RST)
The Reset pin RST is an output that is set LOW when the device is in reset mode. The RST pin is set HIGH when the device
is not in reset mode. RST includes an internal pullup current source. When RST is LOW, the sink current capability is limited,
allowing RST to be shorted to 5.0 V for software debug or software download purposes.
INTERRUPT (INT)
The Interrupt pin INT is an output that is set LOW when an interrupt occurs. INT is enabled using the Interrupt Register (INTR).
When an interrupt occurs, INT stays LOW until the interrupt source is cleared. INT output also reports a wake-up event by a 10
sec. typical pulse when the device is in Stop mode.
GROUND (GND)
This pin is the ground of the integrated circuit.
V2CTRL (V2CTRL)
The V2CTRL pin is the output drive pin for the V2 regulator connected to the external series pass transistor.
VOLTAGE SUPPLY (VSUP)
The VSUP pin is the battery supply input of the device.
HIGH-SIDE OUTPUT 1 (HS1)
The HS pin is the internal high side driver output. It is internally protected against overcurrent and overtemperature.
LEVEL 0-1 INPUTS (L0: L1)
The L0: L1 pins can be connected to contact switches or the output of other ICs for external inputs. The input states can be
read by the SPI. These inputs can be used as wake-up events for the SBC when operating in the Sleep or Stop mode.
