The invention relates to an inductive load driver slew rate controller. A circuit and method for digital controlling the slew rate of load voltage are provided. The circuit is comprised of a digital slew- rate control unit (504, 510) that utilizes a feedback signal (508) to generate control signals (in 501 and 502) where the feedback signal indicates the observed rate of voltage change on the load(505). The circuit is further comprised of a load driver circuit (503, 509) that is operated by the control signals and provides a slew-rate controlled output voltage used to operate a load switch (506, 507), where the load switch provides power to the load. The circuit is configured to operate the load switch using a slew-rate controlling driver, depending on the state of the load switch transition, and a non-controlling driver. 本揭露涉及电感性负载驱动器转换速率控制器。本发明提供种用于数字控制负载电压的转换速率的电路及方法。所述电路由利用反馈信号(508)来产生控制信号(在501及502中)的数字转换速率控制单元(504,510)组成，其中所述反馈信号指示负载(505)上的观测电压变化率。所述电路进步由负载驱动器电路(503,509)组成，所述负载驱动器电路(503,509)由所述控制信号操作且提供用
