Stop:

• Press Stop to deactivate the outputs

Current Feedback:

• Shows current through the high-side FET using the current recopy feature as

interpreted by the KL25Z microcontrollers ADC

Status Fault:

• Shows any fault condition in Sleep mode

Table 11. Logic behind direction control with high-side versus low-side recirculation

Direction

Recirculation

Input signal (INx) generated

Half-Bridge mode (MODE = 0)

IN1 = 1

Forward

high-side recirculation

IN2 = PWM signal with selected duty cycle and frequency

IN1 = PWM signal with selected duty cycle and frequency

Reverse

high-side recirculation

IN2 = 1

IN1 = PWM signal with selected duty cycle and frequency

Forward

low-side recirculation

IN2 = 0

IN1 = 0

Reverse

low-side recirculation

IN2 = PWM signal with selected duty cycle and frequency

Full H-Bridge mode (MODE = 1)

IN1 = 1

Forward

high-side recirculation

IN2 = PWM signal with selected duty cycle and frequency

IN1 = 0

Reverse

high-side recirculation

IN2 = PWM signal with selected duty cycle and frequency
