TIDA-00757: Motor current question

Part Number: TIDA-00757

Hi TI team,


We study the reference design for battery life evalation:TIDA-00757 (Smart Lock Reference Design Enabling 5+ Years of Life on Four AA Batteries (Rev. C)), and we have some questions.



What’s the average output motor current(Iout1,Iout2)?

Could you provide the datasheet of motor with the reference design?

There are just two parameters related current in our selected motor.

  • Rated load current: 1100mA
  • No load crrent: 65mA

How can we use two parameters into equation?


3.3 Motor Driver average Power Consumpation

What’s the average output motor current(Irms1,Irms2)?

How can we find the parameter from datasheet?
