MCZ33889
MCZ33889 is System Basis Chip manufactured by Freescale Semiconductor.
Features
- VDD1: 5.0 V low drop voltage regulator, current limitation, overtemperature detection, monitoring and reset function with total current capability 200 m A
- V2: tracking function of VDD1 regulator; control circuitry for external bipolar ballast transistor for high flexibility in choice of peripheral voltage and current supply
- Four operational modes
- Low standby current consumption in Stop and Sleep modes
- Built-in low speed 125 kbps fault tolerant CAN physical interface.
- External high voltage wake-up input, associated with HS1 VBAT switch
- 150 m A output current capability for HS1 VBAT switch allowing drive of external switches pull-up resistors or relays
- Pb-Free Packaging Designated by Suffix Code EG
