Complementary differential pairs are used to achive a high common-mode voltage range.
common-mode input voltage range
With wide working voltage range can suit wire netting well. lts high duty cycle is applicable for continuous work in factory.
Supply voltage should be controlled at not more than or less than 5% of rated voltage range, if the voltage too high or too low will damage motor.
When battery voltage is less than 5V, voltage range switch should be set to 5V.
