SAM (Supervisor And Monitor)

The ISL6550 is a precision, flexible, VID-code-controlled reference and voltage monitor for high-end microprocessor and memory power supplies. It monitors various input signals, and supervises the system (typically a DC/DC converter) with its output signals. See the Block Diagram for reference.

Features

• 12V supply operation

• 5V reference output

• 5-bit digital-to-analog converter

• Programmable DAC Range, within 0.8–5.0V

• Programmable undervoltage and overvoltage thresholds, and latched fault detection

• Optional delayed undervoltage (programmable with external capacitor)

• Undervoltage lockout (power-on-reset)

• Status Indicators (START, PGOOD)

• Uncommitted operational amplifier

• Compatible with ISL6551 full bridge controller

• 20 Lead SOIC and 20 lead QFN (5x5) packages

Applications

• Power Supplies for High End Microprocessors and Servers

• Can be paired with the ISL6551 FBC for a complete full bridge 48V-input converter, or used independently
