Description

The 33394 is a multioutput power supply integrated circuit with high speed CAN transceiver. The IC incorporates a switching preregulator 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 preregulated 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.
