The invention discloses an intelligent power module and a manufacturing method thereof. The intelligent power module comprises a lead frame arranged on a substrate, and a patch area is arranged at the patch position, corresponding to the lead frame, on the substrate; the upper bridge driving chip and the lower bridge driving chip are arranged in the corresponding patch areas; the power switch device is connected with the upper bridge driving chip and the lower bridge driving chip; an input logic circuit module and a driving circuit module are integrated in the upper bridge driving chip and the lower bridge driving chip so as to receive PWM control signals sent by the main circuit and achieve driving control of a power chip to be driven according to the PWM control signals, gate pole resistance of the driving circuit module is achieved through a first programmable resistance circuit, and gate pole resistance of the driving circuit module is achieved through a second programmable resistance circuit.
