AN INTELLIGENT POWER MOSFET DRIVER ASIC CIRCUIT WITH ADDITIONAL INTEGRATED SAFETY OPERATION FUNCITIONALITY

Abstract

This paper presents an extension to the previously presented conference paper [1] a power MOSFET driver ASIC with intelligent driving algorithm approach of the power modern MOSFET devices. The intelligent driving algorithm concept proposes a realization of power MOSFET gate driving with controlled source/sink current of the power MOSFET driver circuit. Such approach enables higher control of the power MOSFET operation behavior, especially during switching events.  Additionally to the previously published work this paper presents implementation of the intelligent driving algorithm and driver safety operation functions on a single integrated ASIC circuit. The paper concludes with presentation of some functions of the manufactured ASIC circuit in CMOS technology
