This paper presents a fully protected low side switch design from the thermal behavior perspective. The power dissipation is evaluated both for normal operation and for the main high power operation conditions: short circuit and overload, inductive clamping and turn on/off process. Electro-thermal simulations are used to evaluate the surface temperature, that is taken into account in designing the protection functions.

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.
