Abstract
A voltage driver is provided having an input to receive test parameters from a microcontroller. The voltage driver having a first amplifier to provide an input to a first switch, based on the test parameters. The first switch having an output to a first connector such as a probe adapted to be connected to a device under test or DUT. A second switch having an input from a second connector to the device under test, the output of the second switch connected to a ground. A third switch has an input connected to the second switch input, the third switch having an output connected to the first connector to the device under test, wherein the first switch is open, and the second and third switch are closed to set the first connector and the second connector to ground. A buffer is provided such that the microcontroller is sets the test parameters in the first voltage driver, the first voltage driver is adapted to provide test data to the buffer. The device is set such that all of the inputs may be set to ground to minimize the possibility of electrostatic discharge building up on the probes and damaging the DUT.
