Claim 11:
12. A method of regulating a slew time of an output voltage of a motor driver system, comprising:
receiving a target slew time;
comparing an output voltage of the driver system with an upper reference voltage and a lower reference voltage;
providing a start signal and an end signal based on the comparison, wherein the start signal indicating when a transistor transitions to a linear region and the end signal indicating when the transistor transitions to a non-linear region;
determining a slew time based on a duration between assertion of the start signal and assertion of the end signal; and
increasing a gate current responsive to the slew time being greater than the target slew time and decreasing the gate current responsive to the slew time being less than the target slew time.
