Question

Find the datasheet for both the UK 1122 and L298N How do the two components relate to one another? For the L298N, what is the difference between and V_ss? Assume you have only a 15V battery and we want V_ss = 5V and Vs = 12V. What component (s) can you add to make this possible. Draw diagram of how the battery is connected to V_s and V_ss (include other components if necessary.) What is the typical commutation frequency that can be used with the L298N chip? Assuming V_s = 20V and V_ss = 5V, what percent high PWM signal should you input (to input 1) to achieve an average of 5V (at output 1)? Using the L298N, with V_s = 20V and the motor connected to pin 1 and 2 and assume your motor is the equivalent resistance of 5Ohm and can handle full voltage. Using only input 1, what percent high duty cycle should you input if you want to attain the max constant speed (unloaded)?

Explanation / Answer

A) UK1122 is dual bidirectional motor driver is based on the very popular L298 Dual H-Bridge Motor Driver Integrated Circuit. The circuit will allow you to easily and independently control two motors of up to 2A each in both directions.

Whereas L298N is a full bridge driver.

B) Vs is a power supply and Vss is a Logic supply voltage.

C) typical communicatin frequency is 25 KHz.
