ABSTRACT:
A differential current mode driver is provided with output source and sink currents that remain nearly equal in magnitude and opposite in direction throughout normal, power-down, and power-up modes of operation. Three time constants are employed to regulate these different modes of operation. The differential current mode driver includes a first time constant to stabilize the output source and sink currents during the on-state, a second time constant to control the transition from the on-state to tristate, and a third time constant to control the transition from tristate to the on-state, all the while maintaining equal source and sink currents.
