Abstract :
This paper presents the design and the laboratory results of an integrated half-bridge driver for power electronic systems in a 0.35 mum bipolar CMOS DMOS (BCD) technology. The proposed solution is designed for frequency applications up to several hundred of KHz and it has a driving current capability up to 50 mA. This work features a design configuration and a digital control to reduce electromagnetic interference (EMI). Moreover it includes short circuit protection, programmability of voltage references and a digital control circuitry implementing mechanism to prevent dangerous failures of the driver. After a deep description of the circuit we show the laboratory results of the half-bridge driver used to drive a 20 KHz antenna.
