MAX16543GPC+ by Analog Devices

Integrated Protection IC on a High-Power 12V Bus with an Integrated MOSFET and Lossless Current Sensing


The MAX16543 is an integrated follower protection IC that is used in parallel with a Maxim MAX16545B/ MAX16545C master integrated protection IC for distribution, control, monitoring and protection of a system’s 12V bus. The MAX16543 increases the current capability of the MAX16545B/MAX16545C. The MAX16545B/ MAX16545C provide the reporting and fault protection circuits for the combined chipset. Up to two MAX16543s can be added to a MAX16545B/MAX16545C IC to provide DC current capability of more than 60A. The 1.8V bias supply and gate drive voltage supply of the MAX16543 are powered by the MAX16545B/MAX16545C. All features of the MAX16545B/MAX16545C remain available when a MAX16543 is added to the circuit. The chipset provides monotonic startup with programmable ramp and delay to limit inrush current during startup. The total current is monitored and reported. Programmable system overcurrent protection is provided with several levels of protection. The MAX16543 includes Maxim’s patented lossless current sense to provide high accuracy current sensing through the MAX16545B/MAX16545C IC. The MAX16543 reports its current to the MAX16545B/MAX16545C, which then reports the total current. The MAX16543 is controlled entirely by the MAX16545B/ MAX16545C IC. The chipset input and output voltage fault protection is provided by the MAX16545B/MAX16545C, which enables and disables the MAX16543 as commanded by circuit conditions and command signals. Master + 1 Follower Chipset and Master + 2 Follower Chipsets show the basic application circuits for the master/follower chipset, with single and dual MAX16543s working in tandem to provide higher current ratings than a single MAX16545B/MAX16545C.
