MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
The 33394 is a multi–output power supply integrated circuit with high
speed CAN transceiver. The IC incorporates a switching pre–regulator
operating over a wide input voltage range from +4.0V to +26.5V (with
transients up to 45V).
The switching regulator has an internal 3.0A current limit and runs in both
buck mode or boost mode to always supply a pre–regulated output followed
by Low Drop Out (LDO) regulators: VDDH / 5.0V @ 400mA; VDD3_3 / 3.3V
@ 120mA; VDDL / 2.6V (User scalable between 3.3V – 1.25V) @ 400mA
typically, using an external NPN pass transistor. The Keep Alive regulator
VKAM (scalable) @ 50mA; FLASH memory programming voltage VPP /
5.0V or 3.3V @ 150mA; three sensor supply outputs VREF(1,2,3) / 5.0V
(tracking VDDH) @ 100mA each; and a switched battery output (VSEN) to
supply 125mA clamped to 17V.
Additional features include Active Reset circuitry watching VDDH,
VDD3_3, VDDL and VKAM, user selectable Hardware Reset Timer (HRT),
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 and differential bus lines. 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
the MPC565 microcontroller, though it will also support others from the
MPC5XX family of Motorola microcontrollers.
Features:
Wide operating input voltage range: +4.0V to +26.5V (+45V transient).
Provides all regulated voltages for MPC5XX MCUs and other ECU’s
logic and analog functions.
Accurate power up/down sequencing.
Provides necessary MCU support monitoring and fail–safe support.
Provides three 5.0 V buffer supplies for internal & external (short–circuit
protected) sensors.
Includes step–down/step–up switching regulator to provide supply
voltages during different battery conditions.
Interfaces Directly to Standard 5.0V I/O for CMOS Microprocessors by
means of Serial Peripheral Interface.
