ISL6131, ISL6132 ® Data Sheet August 17, 2010 Multiple Voltage Supervisory ICs Features The ISL6131 and ISL6132 are a family of high accuracy multi voltage supervisory ICs designed to monitor voltages greater than 0.7V in applications ranging from microprocessors to industrial power systems. The ISL6131 is an undervoltage four supply supervisor whereas the ISL6132 is a two voltage supervisor monitoring both for undervoltage (UV) and overvoltage (OV) conditions. • Operates from 1.5V to 5.5V Supply Voltage Both ICs feature four external resistor programmable voltage monitoring (VMON) inputs each with a related STATUS output that individually reports the related monitor input condition. In addition there is a PGOOD (power good) signal that asserts high when the STATUS outputs are in their correct state. There is a stability delay of approximately 160ms to ensure that the monitored supply is stable before STATUS and PGOOD are released to go high. The PGOOD and STATUS outputs are open-drain to allow ORing of the signals and interfacing to a wide range of logic levels. STATUS and PGOOD outputs are guaranteed to be valid with IC bias lower than 1V eliminating concern about STATUS and PGOOD outputs during IC bias up and down. VMON inputs are designed to ignore momentary transients on the monitored supplies. • Four Adjustable Voltage Monitoring Thresholds • 150ms STATUS/PGOOD Stability Time Delay • Four Individual Open Drain STATUS Outputs • Guaranteed STATUS/PGOOD Valid to VDD <1V • VDD and VMON Glitch Immunity • VDD Lock Out • 4mm X 4mm QFN Package • 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 • Pb-Free (RoHS Compliant) Applications • Multivoltage DSPs and Processors • µP Voltage Monitoring • Embedded Control Systems • Graphics Cards Ordering Information PART NUMBER FN9119.4 • Intelligent Instruments TEMP.

Upon VDD bias power up, the STATUS and PGOOD outputs are held correctly low once VDD is as low as 1V. Once biased to 1.5V the IC continuously monitors from one to four voltages independently through external resistor dividers comparing each voltage monitoring (VMON) pin voltage to an internal 0.633V (VVMONvth) reference. With the EN input driven high or open as each VMON input rises above VVMONvth a timer is set to ensure ~160ms of continuous compliance then the related STATUS output is released to be pulled high. The STATUS outputs are opendrain to allow ORing of these signals and interfacing to a logic high level up to VDD. The STATUS are designed to reject short transients (~30μs) on the VMON inputs. Once all STATUS outputs are high a power good (PGOOD) output signal is generated high to indicate all the monitored voltages are greater than minimum compliance level. Once any VMON input falls below VVMONvth for longer than the glitch filter time both the PGOOD and the related STATUS output are pulled low. The other STATUS outputs will remain high as long as their corresponding VMON voltage remains valid and the PGOOD validation process is reset. Figure 1 illustrates ISL6131 typical application schematic and Figure 3 is an operational timing diagram. See Figures 10 to 17 for ISL6131 function and performance. Figures 10 and 11 show the VDD rising along with STATUS and PGOOD response. Figures 12 and 13 illustrate VMON falling below VVMONvth and Figure 14 illustrates VMON rising above VVMONvth with STATUS and PGOOD response. Figure 15 shows the VDD failing with STATUS and PGOOD response. Figures 16 and 17 illustrate ENABLE to STATUS and PGOOD timing. If less than four voltages are being monitored, connect the unused VMON pins to VDD for proper operation. All unused STATUS outputs can be left open. The ISL6132 is a dual voltage monitor for under and overvoltage compliance. Figure 2 illustrates the typical ISL6132 implementation schematic and Figure 4 is the operational timing diagram. There are 2 pairs of monitors each with an undervoltage (UVMON) input and overvoltage (OVMON) input along with with associated STATUS and PGOOD outputs. Upon VDD bias power up, the STATUS and PGOOD outputs are held correctly low once VDD is as low as 1V. Once biased to 1.5V the IC continuously monitors the voltage through external resistor dividers comparing each VMON pin voltage to an internal 0.633V reference. At proper bias the OVSTATUS are pulled high and the UVSTATUS and 5 PGOOD are pulled low. Once the UVMON input > the VMON Vth continuously for ~160ms, its associated STATUS output will release high indicating that the minimum voltage condition has been met. As both UVMON and OVMON inputs are satisfied the PGOOD output is released to go high indicating that the monitored voltage is within the specified window. Figure 18 illustrates this performance for a 4V to 5V window. When VMON does not satisfy its voltage high or low criteria for more than the glitch filter time, the associated STATUS and PGOOD are pulled low. Figures 19 and 20 illustrate this performance for a 4V to 5V compliant window. Figures 21-23 illustrate the VMON glitch filter timing to STATUS and PGOOD notification and transient immunity. The ENABLE input when pulled low allows for monitoring and reporting function to be disabled. Figure 24 shows ENABLE high to PGOOD timing for compliant voltage. When choosing resistors for the divider remember to keep the current through the string bounded by power loss tolerance at the top end and noise immunity at the bottom end. For most applications total divider resistance in the 10kΩ -100kΩ range is advisable with 1% tolerance resistors being used to reduce monitoring error. Referencing Figures 1 and 2, choosing the two resistor values is straightforward for the ISL6131 as the ratio of resistance should equal the ratio of the desired trip voltage to the internal reference, 0.633V). For the ISL6131, two dividers of two resistors each can be employed to monitor the OV and UV levels for each voltage. Otherwise, use a single three resistor string for each voltage. In the three resistor divider string the ratio of the desired over voltage trip point to the internal reference is equal to the ratio of the two upper resistors to the lowest (GND connected) resistor. The desired under voltage trip point ratio to the internal reference voltage is equal to the ratio of the uppermost (voltage connected) resistor to the lower two resistors. An example follows; 1. Establish lower and upper trip level: 3.3V ±20% or 2.64V (UV) and 3.96V (OV) 2. Establish total resistor string value: 10kΩ, Ir = divider current 3. (Rm+Rl)*Ir = 0.623V @ UV and Rl * Ir = 0.633V @ OV 4. Rm+Rl = 0.623V / Ir @ UV => Rm+Rl = 0.623V / (2.64V /10kΩ) = 2.359kΩ 5. Rl = 0.633V / Ir @ OV => Rl = 0.633V /(3.96V/10kΩ) = 1.598kΩ 6. Rm = 2.359kΩ - 1.598kΩ = 0.761kΩ 7. Ru = 10kΩ - 2.397kΩ = 7.641kΩ 8. Choose standard value resistors that most closely approximate these ideal values. Choosing a different total divider resistance value may yield a more ideal ratio with available resistors values.

Additional ISL6131s can be employed in parallel to sequence any number of DC-DC convertors is in this fashion. The ISL613XSUPEREVAL2 platform is the primary evaluation board for this family of supervisors and is designed to support the ISL6131, ISL6132. In addition, it also supports the ISL6125 sequencer as it has open drain RESET# outputs similar to the STATUS outputs of the ISL6131 and ISL6132. VIN EN VIN The ISL613XSUPEREVAL2 is shipped with a ISL6125 soldered into the SMD channel 2 position and with 2 each of the ISL6131 (1 socketed) and ISL6132 loose packed. The four resistor divider strings are set so that VMON = VMON Vth (0.633V) once supplies are 2.10V on the IN_D, 1.27V on IN_C, 4.27V on IN_B and 2.78V on IN_A. On the ISL6131 these are the 4 UV levels at ~85% of 2.5V, 1.5V, 5V and 3.3V respectively. LEDs turned off are the PGOOD high indicators with D4 being the ISL6131 indicator. With VDD ranging from 1.5V to 5V or shorted to IN_A through JP1 and with an ISL6131 in the socket, PGOOD will release to be pulled high once those minimum conditions are met. See Figures 10 to 17 for performance and function examples. With the ISL6132 in the socket and IN_C and IN_D tied to a common supply and IN_A and IN_B tied to a second supply the ISL6132 will look for a voltage between 1.27V to 2.10V on the CD pair and between 2.78V and 4.27V for the AB pair. Once either supply meets its requirement the related PGOOD will release to pull high and turn off the related LED. See Figures 18 to 24 for performance and function examples. Figures 25 and 26 illustrate the ISL613XSUPEREVAL2 platform in image and schematic. Using the ISL6131, ISL6132 for Negative Voltage Monitoring Applications The ISL6131, ISL6132 can be used for -V monitoring as it monitors any voltage more positive relative to its GND pin. With correct bias differential these parts can monitor any voltage regardless of polarity or amplitude. Using the ISL6131 for ‘Loss Less’ Sequencing Applications The ISL6131 can be used in a ‘loss less’ sequencing application where a monitored output voltage determines the start of the next sequenced turn-on. As shown in Figure 7, VMON_A input looks at the common VIn of several DC-DC converters and enables DC-DC_A with STATUS _A, once both VIn and ENABLE are satisfied. VMON_B monitors the output of DC-DC_A and when the acceptable output voltage is reached, DC-DC_B is enabled with STATUS_B output. This sequencing pattern is continued until all DC-DC outputs are on, at which time PGOOD signal will be released to indicate. 160ms delay from VMON > VVMONVth to STATUS high ensures stability at each step prior to subsequent turn7 EN VIN EN ABC STATUS PGOOD VOUT DC-DC_A VOUT DC-DC_B VOUT DC-DC_C VMON_A VMON_D ISL6131 VMON_C VDD ENABLE VMON_B GND FIGURE 7. ISL6131 ‘LOSSLESS’ SEQUENCING CONFIGURATION Using the ISL6131 for System Voltage and Over Temperature Monitoring Being a multivoltage monitoring IC the ISL6131 can also be used to monitor over temperature as well as voltage for a more complete coverage of system health. Using a Negative Temperature Coefficient (NTC) passive device in place of one of the resistors in a VMON divider provides over temperature monitoring either locally or remotely. Evaluations of this application configuration have involved the QT0805T-202J, QT0805Y-502J and QT0805Y-103J NTCs from Quality Thermistor. ISL6131 over temperature monitoring is not as accurate as specific temperature monitor ICs but this implementation provides a cost efficient solution with 5% tolerances achievable. See Figures 8 - 9 for over temp sensing configuration and operation results. In this example, the desired maximum temp is 100°C. The QT0805Y-103J NTC was placed at the end of 3 feet of twisted pair wire to emulate a remote sensing application. From the Quality Thermistor data sheet, this NTC device has a +25°C value of 10K and at +100°C a value of 0.923K. An accompanying standard value resistor of 3.83K was chosen for divider so that at 100°C, VMON ~0.633V with the bias voltage at 3.3V. FN9119.4 August 17, 2010 ISL6131, ISL6132 The resulting falling VMON trip point with configuration shown is ~0.634V, with ~0.642V for rising which equates to ~95°C for under temperature and ~97°C for over temperature respectively. Choosing the standard resistor value above and below R1 allows for small adjustments in the temperature trip point. The low ISL6131 VMON temperature coefficient makes this a viable and low cost addition to complete system monitoring.
