Claim 7:
8. A motor driver system, comprising:
a low-side transistor having a first terminal, a second terminal coupled to a ground terminal, and having a control terminal;
a comparison circuit having a first input, a second input adapted to be coupled to an upper reference voltage, a third input adapted to be coupled to a lower reference voltage and an output;
a slew time detection circuit having a first input adapted to receive a pulse width modulated (PWM) signal and a second input coupled to the output of the comparison circuit and an output;
a gate current control circuit having a first input coupled to receive a target slew time and a second input coupled to the output of the slew time detection circuit and an output; and
a gate driver having a first input coupled to receive a low-side PWM signal and a second input coupled to the output of the gate current control circuit, the gate driver having an output coupled to the control terminal.
