Abstract

A hot swap controller IC was designed to ensure the safe insertion and removal of a circuit board from a live backplane. Multi protections including that against inrush current as well as the short circuit, load glitches, over-voltage and under-voltage occurring of both board and backplane were proposed in this design. Due to introduction of the Analog, Bipolar, CMOS and DMOS (ABCD) compatible technology, its circuit structure was simplified while the high drive capability was attained. In addition, a high side switch driver controls the N-channel gate for supply voltages ranging from 4.5V to 16.5V. It consumes 18 mW at 12.0 V. During the design, the system architecture, circuit and layout was simulated and optimized. The final chip occupied 2.5 x 2.0mm²and was taped-out in NSC´s 1.5um ABCD technology. Test shows that the expected functions was achieved and the main features met the requirements well.
