Microcontroller with LIN and Power Switches for Automotive Applications
Power Management Unit (PMU)
Features
• 5 V low-drop voltage regulator
• Overcurrent monitoring and shutdown with MCU signalling (Interrupt)
• Overvoltage monitoring with MCU signalling (Interrupt)
• Undervoltage monitoring with MCU signalling (Interrupt)
• Undervoltage monitoring with Reset (Undervoltage Reset,
V
DDPUV
)
• Overtemperature shutdown with MCU signalling (Interrupt)
• Pre-Regulator for VDDC Regulator
• GPIO Supply
• Pull Down Current Source at the output for Sleep Mode only (typ.5 mA)
The output capacitor
C
VDDP
is mandatory to ensure a proper regulator functionality.
