Abstract
Dual-channel 0.5 A high-side intelligent power distribution switch with overcurrent and overtemperature circuit protection and soft start feature is proposed in this paper. The switch is dedicated to use in portable USB devices. Besides that, another motivation was to use the switch as a mixed-signal test vehicle to evaluate feasibility of current sensors for on-chip current testing. Parameters and features of the switch were investigated for a wide temperature range and process variations. The proposed power switch was designed in a standard CMOS technology and it is being physically implemented in 0.35 mum process by AMS.
