FU6333N

Feature

• Power supply:
• Single-power supply mode: When VCC_MODE = 0, external power supply 5V ~ 28V is connected to VCC pin, and internal LDO supplies VDD5 voltage.
• Low-voltage single-power supply mode: When VCC_MODE = 1, external power supply 3V ~ 5.5V is connected to VDD5 pin, and VDD5 pin is shorted to VCC pin.
• Dual-power supply mode: When VCC_MODE = 1, external power supply 1 (5V ~ 36V) is connected to VCC pin, and external power supply 2 (5V) is connected to VDD5 pin.
