Abstract
According to some embodiments, a magnetic secured transmission (MST) driver is provided. The MST driver includes a full-bridge switching circuit that includes a first half-bridge coupled to a first node and a second half-bridge coupled to a second node; and a control circuit coupled to drive the first half-bridge according to MST input data and to drive the second half bridge according to a high-frequency pulse width modulation (PWM) signal.
