Multiple Voltage Supervisory ICs ISL6131, ISL6132 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, and the ISL6132 is a two-voltage supervisor monitoring 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 Power-Good (PGOOD) signal that asserts high when the STATUS outputs are in their correct state. A stability delay of approximately 160ms ensures 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 OR’ing of the signals and interfacing to a wide range of logic levels. • VDD Lock-Out 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. • Multivoltage DSPs and Processors • 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 • 4mm X 4mm 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 • µP Voltage Monitoring • Embedded Control Systems • Graphics Cards • Intelligent Instruments • Medical Equipment • Network Routers • Portable Battery-Powered Equipment • Set-Top Boxes VMON_A GROUND VMON_B VMON_D UVMON_2 GROUND FIGURE 1.

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 open-drain to allow OR’ing of these signals and interfacing to a logic high level up to VDD. The STATUS outputs 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 that all 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 remain high as long as their corresponding VMON voltage remains valid and the PGOOD validation process is reset. Figure 1 shows the 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 shows VMON rising above VVMONvth with STATUS and PGOOD response. Figure 15 shows VDD failing, with STATUS and PGOOD response. Figures 16 and 17 show 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 undervoltage and overvoltage compliance. Figure 2 shows the typical ISL6132 implementation schematic, and Figure 4 is the operational timing diagram. There are two pairs of monitors, each with an undervoltage (UVMON) input and an overvoltage (OVMON) input, along 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, OVSTATUS is pulled high, and UVSTATUS and PGOOD are pulled low. Once the UVMON 5 input > VMON Vth continuously for ~160ms, its associated STATUS output releases 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 shows 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 show this performance for a 4V to 5V compliant window. Figures 21 through 23 show the VMON glitch filter timing to STATUS and PGOOD notification and transient immunity. The ENABLE input, when pulled low, allows the monitoring and reporting functions 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. Figures 1 and 2 show that choosing the two resistor values is straightforward for the ISL6131, because the ratio of resistance should equal the ratio of the desired trip voltage to the internal reference, 0.633V. For the ISL6132, 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 overvoltage trip point to the internal reference is equal to the ratio of the two upper resistors to the lowest (GND connected) resistor. The desired undervoltage trip point ratio to the internal reference voltage is equal to the ratio of the uppermost (voltage connected) resistor to the two lower resistors, as shown in the following example: 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 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.

VIN EN EN Each monitored supply has an individual STATUS output and an AND’ed PGOOD output signal for all four supplies. An OFF LED is the PGOOD indicator for all four supplies. The ENABLE input enables or disables the voltage monitoring function. See Figures 10 to 17 for performance and function examples. The ISL6132EVAL1Z platform is set up to monitor and report either an undervoltage or an overvoltage condition on 5V and 12V supplies to a ±10% tolerance. There is an OV and a UV STATUS output for each of the two supplies and individual AND’ed PGOOD outputs when each voltage is within the programmed voltage range. An OFF LED indicates compliance to the voltage range upper and lower limits. The ENABLE inputs enable or disable the voltage monitoring functions for each monitor supply. See Figures 18 to 24 for performance and function examples. Figures 25 and 26 illustrate the ISL6131EVAL1Z and ISL6132EVAL1Z platforms respectively in image and schematic.

ISL6131 “LOSSLESS” SEQUENCING CONFIGURATION Using the ISL6131, ISL6132 for Negative Voltage Monitoring Applications Using the ISL6131 for System Voltage and Over-Temperature Monitoring The ISL6131, ISL6132 can be used for -V monitoring because it monitors any voltage that is more positive relative to its GND pin. With correct bias differential, these parts can monitor any voltage, regardless of polarity or amplitude. As a multi-voltage monitoring IC, the ISL6131 can monitor over-temperature as well as voltage for more complete coverage of system stability. 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. Using the ISL6131 for “Lossless” Sequencing Applications The ISL6131 can be used in a “lossless” sequencing application in which 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 continues until all DC-DC outputs are on, at which time PGOOD signal is released. A delay of 160ms from VMON > VVMONVth to STATUS high ensures stability at each step prior to subsequent turn-on. Additional ISL6131s can be employed in parallel to sequence any number of DC-DC convertors in this fashion. 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 and 9 for over-temperature sensing configuration and operation results. In this example, the desired maximum temperature 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. According to the Quality Thermistor data sheet, this NTC device has a +25°C value of 10K and a +100°C value of 0.923K. An accompanying standard value resistor of 3.83K was chosen for the divider so that at 100°C, VMON ~0.633V with the bias voltage at 3.3V. The resulting falling VMON trip point with the 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. 7 FN9119.6 February 11, 2014 ISL6131, ISL6132 The low ISL6131 VMON temperature coefficient makes it a viable and low-cost addition to complete system monitoring.
