A voltage divider circuit regarding a battery voltage and an associated electronic device equipped with the voltage divider circuit are provided. The voltage divider circuit may include a first level shifter circuit, a second level shifter circuit and a controlled voltage divider. The first level shifter circuit selectively performs a first level shifting operation on an original enable signal according to respective voltage levels of multiple control signals to generate a first enable signal. The second level shifter circuit selectively performs a second level shifting operation on the first enable signal according to a voltage level of the first enable signal to generate a second enable signal. The controlled voltage divider selectively performs a voltage dividing operation on the battery voltage according to a voltage level of the second enable signal to generate a divided voltage of the battery voltage to be an output of the voltage divider circuit.
