Abstract
[Problem to be solved] The disclosure is to deal with a wide range of DC voltages in the input. [Solution] In a current sense amplifier, an upper side voltage and a lower side voltage of a current detection resistorare input thereto, and an output corresponding to a difference between the upper side voltage and the lower side voltage is obtained. A common mode voltage suppressorincludes: voltage division resistors Rand R, the upper side voltage and the lower side voltage being supplied to the two ends thereof, and a division voltage being obtained; a first transistor M, the upper side voltage being input to one end thereof, and the other end thereof being connected to a predetermined power supply; and a second transistor M, the lower side voltage being input to one end thereof, and the other end thereof being connected to a predetermined power supply. A control end of the first transistor Mand a control end of the second transistor Mare commonly connected and the division voltage is input thereto.
