Short circuit protection in dual configurable high side switch

Abstract: This paper presents a fully protected high side switch design from the short circuit perspective. The high side switch is dual configurable: either 7 Ω or 2 Ω in terms of ON resistance, each with its short circuit current limitation level. The circuit was implemented in a BCD technology, where the key for area efficiency is making use as much as possible of the low voltage components. This is especially difficult for high side switch design, where the circuit is referred to the high voltage car battery.
