Abstract
A powered surgical instrument disclosed. The instrument includes a first circuit portion operable at a first voltage level, a second circuit portion operable at a second voltage level, a voltage source to supply the first voltage level to supply power to electrical components in the first circuit portion; a transistor comprising a control terminal, a first conduction terminal, and a second conduction terminal, and a control circuit coupled to the control terminal of the transistor. The second voltage level is different from the first voltage level. The first conduction terminal is coupled to the voltage source. The control circuit is to set the transistor in a linear mode and control the transistor to set a current for operating the motor.
