Freescale MC33889 System Basis Chip Datasheet
The MC33889 is a System Basis Chip (SBC) that integrates a 5.0 V low‑dropout regulator, power‑management functions, a programmable watchdog, SPI interface and a low‑speed 125 kbps fault‑tolerant CAN transceiver for MCU‑based designs. It supports multiple power modes (Normal, Standby, Stop, Sleep) and offers an external high‑side switch capability.
Key features include a 200 mA regulated VDD1 output, a tracking V2 regulator, 150 mA output capability for the HS1 VBAT switch, and a 28‑pin SOICW package. The datasheet details pin assignments, maximum ratings, and static electrical characteristics for reliable system integration.
