The MST driver is configured to transmit magnetic strip data comprising of streams of pulses. The MST driver comprises a pair of high side switches and a pair of low side switches. The pair of high side switches comprises a first switch and a second switch. The pair of low side switches comprises a third switch and a fourth switch. The first, second, third and fourth switches are arranged in a full bridge type configuration connected across a voltage source and a ground. An inductive coil is connected across outputs of the full bridge type configuration of the switches. The MST driver includes a switch driver configured to drive the pair of low side switches and the pair of high side switches under current slope control using pulse width modulation. The driven load current has a rising portion and a falling portion through the inductive coil in a forward direction or in a reverse direction with programmable load current rising and falling slopes to induce a recognizable back electromagnetic force at a receiver emulating the magnetic strip data during the load current rising and falling portions and to reduce power loss during time periods without signal transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic stripe data transmission system and method for reliable data transmission and low power consumption","description":"A magnetic stripe data transmission (MST) driver and a method for driving the MST are disclosed.
