(Model; FU6832S package; SSOP24 original stock in stock)

Single power supply high voltage mode: VCC_MODE=0, the external power supply is input from VCC to 5~28V, and VDD5 is generated by the internal LDO

Single power supply low voltage mode: VCC_MODE=1, the external power supply inputs 3~5.5V from VDD5, and short-circuits VCC and VDD5 at the same time

Dual power supply mode: VCC_MODE=1, external power supply 1 inputs 5~36V from VCC, and external power supply 2 inputs 5V from VDD5
