Abstract
A data transmitter high side switch includes at least one output unit, an input logic unit, a reset circuit coupled to the input logic unit, a capacitor pump circuit coupled to the reset circuit and the input logic circuit, and operatively to the at least one output unit. The capacitor pump circuit includes at least one capacitor that is charged in a first direction during a time period when the input data signal is in a first logic level. During a subsequent time period, when the input data signal is in a second logic level, a reference voltage for the charge on the capacitor is changed to thereby provide an overdrive level turn-on voltage to a corresponding output transistor of the at least one output unit. The charge of the at least one capacitor can be adjustably selected to compensate for tolerance variations and/or ambient conditions to control output impedance.
