EA uniTFTm Series

The module has the option of controlling external components via a PWM signal (pulse width modulation). At constant frequency (adjustable from 20 Hz to 1.5 MHz #HFO), the duty cycle of a rectangular pulse is changed. Modulation changes the ratio between the on- and off-time and thus the characteristics of the output signal. In this way, electromechanical components such as motor or lamp can be driven or even a quasi-analogue voltage can be generated. The variation of the duty cycles supports a low engine speed/voltage with a short start-up time or a high motor speed/voltage with a long start-up time. The output levels are at 0V and VDD.
