Abstract:
A noise resistant switch control circuit is provided. The circuit includes a low pass filter configured to couple to a first terminal of a switch and a first voltage clamp coupled to the low pass filter. The first voltage clamp is configured to couple to a control terminal of the switch and limit a voltage of the control terminal relative to the first terminal to within a first clamping range. The circuit includes a second voltage clamp coupled to an input terminal of the switch control circuit. The second voltage clamp is configured to couple to the control terminal of the switch. The second voltage clamp is further configured to reduce a level of a control voltage coupled to the second voltage clamp. The circuit includes a bias device configured to couple to the control terminal of the switch and to impress a biasing voltage to the control terminal.
