SAM (Supervisor And Monitor)

Features

• 12V supply operation

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.

• 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

The ISL6550 includes a 5-bit DAC (Digital-to-Analog

Converter), which is programmed by the five VID inputs. The

voltage range of the BDAC (Buffered DAC output) is

determined by the DACHI and DACLO voltage levels, which

are externally adjustable through the R1, R2, R3 resistor

divider network. VREF5 is a precision-trimmed 5V reference,

and is used to set the voltage at the top of the resistor

divider.

• 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

• QFN Package:

- Compliant to JEDEC PUB95 MO-220

QFN - Quad Flat No Leads - Package Outline

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile

Programmable window comparators monitor Overvoltage

(OV) and Undervoltage (UV) levels. The OVUVSEN input,

usually coming from the associated power converter device

is monitored and compared with BDAC; an error band is

established via the R4 and R5 resistor setting on the

OVUVTH pin. An optional external capacitor on the UVDLY

pin gives a programmable delay on the UV. A high gain

operational amplifier is available at pins VOPP, VOPM, and

VOPOUT; it can be used as a gain stage to permit

Applications

• Power Supplies for High End Microprocessors and Servers

monitoring voltages that are different from the BDAC levels.

The PEN (Power supply ENable) input, driven from an open-

collector source, enables (when logic high) the external

converter output, via the PGOOD or START outputs (both

open-drain). They both basically indicate that the power

supply is enabled (PEN = high) and there are no fault

conditions. There are two logic options available, which

determine the START and PGOOD states; see the block

diagram or the Logic Options Table for more detail. The two

logic options are identified with a suffix letter A or C in the

ordering information.

• Can be paired with the ISL6551 FBC for a complete full-

bridge 48V-input converter, or used independently
