... This enables new cost effective board design possibilities to achieve complex mechatronic solutions. The Atmel ATA6832C is a triple half-bridge driver to control up to three different loads by a microcontroller in automotive and industrial applications. Each of the three high-side and three low-side drivers is capable of driving currents up to 1.0A. Due to the enhanced PWM signal (up to 25kHz possible to generate a smooth control of, for example motor without any noise ...
