i am using L298N h-bridge with Raspberry pi to drive my motors. I am using 4 motors and each motor is of 3V and 120mA. But, my teacher has asked me to shift to powerful motors and i have bought 2 new motors having the following features:

  • Output speed: 150±10%rpm
  • No-load current: 200mA (Max)
  • Stall current: 4500mA(max)
  • Stall torque: 9.5kgNaN
  • Rated speed: 100±10%rpm
  • Rated torque: 3000gNaN
  • Rated current: 1200mA (Max)
  • Noise :56dB
  • Working voltage: 9V
  • Outside Shaft Length: 14.5mm
  • Shaft End Play: 0.05-0.50mm
  • Screw Size: M3.0
  • Dia. Of Shaft phi 4mm, D3.5

My question is what h-bridge should i use with these motors having a stall current of 4500mA and rated current of 1200mA? As the L298N h-brige supports peak current value of 2000mA that too for only few seconds.

You could alternatively use TIP120 or other transistors if you want to still use your H-bridge and ramp up the power with the transistor.
