ADM1175 OVERVIEW OF THE HOT SWAP FUNCTION When circuit boards are inserted into a live backplane, discharged supply bypass capacitors draw large transient currents from the backplane power bus as they charge. Such transient currents can cause permanent damage to ...
Page 13
GATE AND TIMER FUNCTIONS DURING A HOT SWAP OPERATION During hot insertion of a board onto a live supply rail at VCC, the abrupt application of supply voltage charges the external FET drain/gate capacitance, which can cause an unwanted gate ...

ADM1175 When the initial timing cycle terminates, the device is ready to start a hot swap operation (assuming that the ON/ONB pin is asserted). In the example shown in Figure 30, the ON pin is asserted at the same time ...
