MC33394 : Power Oak
The 33394 is a multi-output power supply device with high speed CAN transceiver. The IC incorporates a
step-up/step-down switching pre-regulator, high operates over a wide input voltage range from 4.0 V to
26.5 V with transients up to 45 V. The following low drop out linear regulators provide several different
output voltages to supply the microcontroller core and I/O, FLASH memory, sensors and other circuits.
Active reset circuitry protects the data coherency of the microcontroller any time one of the three core
voltages goes out of regulation. Power sequencing circuitry guarantees the core supply voltages never
exceed their limits or polarities during system power up and power down. A high speed CAN transceiver
physical layer interfaces between the microcontroller CMOS outputs. The CAN driver is short circuit
protected and tolerant of loss of battery or ground conditions. 33394 is designed specifically to meet the
needs of modules, which use advanced 32-bit microprocessor architectures like the Motorola MPC5xx and
MPC824x microcontroller families.
