FEATURES & APPLICATIONS • Loss-Less Tracking function - No power MOSFET switches • Programmable Slew-Rate, Tracking and Voltage Monitoring Functions • Directly Interfaces to DC-DC Converters, Monolithic Controllers or LDOs • Programmable Sequence Orders • Programmable Tracking Slew Rates • Eliminates Series Power MOSFETs • Programmable OV/UV Threshold Limits • Under Voltage Lock-Out (VDD and VCTRL_SUP) • 4k-Bit user configurable Nonvolatile Memory • I2C 2-wire serial bus for programming configuration and monitoring status Applications • Monitor, Sequence and Slew-Rate Control of Distributed Power and Point of Use Power Supplies • Multi-voltage Processors, DSPs, ASICs used in Telecom, CompactPCI or server systems INTRODUCTION The SMT4504 is an intelligent power supply sequencer, tracker, and voltage monitor. The SMT4504 tracks or sequences up to 4 power supplies by uniquely controlling the Enable and TRIM (Soft- Start) functions of DC-DC converters, Monolithic Controllers or LDOs. Each Channel is individually programmable for undervoltage/overvoltage threshold settings, sequence position and slew rates. Two or more supplies allocated to the same sequence position are tracked, while assigning individual supplies to a unique sequence position causes them to be sequenced with controlled slew rates. The SMT4504 monitors the supplies for faults and is programmable to take any of several actions upon the occurrence of a fault. The voltage monitoring threshold step size is better than ±1%. Power supply sequencing can be executed in any order. During power-off sequencing, the SMT4504 sequences the supplies in the reverse order as power- on. Using the I 2C interface, a host system can communicate with the SMT4504 status register, optionally control power-on/off software and utilize 4K- bits of nonvolatile memory.
