DATASHEET ISL6131, ISL6132 FN9119 Rev 6.00 Multiple Voltage Supervisory ICs February 11, 2014 The ISL6131 and ISL6132 are a family of high-accuracy, Features multi-voltage supervisory ICs designed to monitor voltages Operates from 1.5V to 5.5V Supply Voltage greater than 0.7V in applications ranging from microprocessors to industrial power systems. The ISL6131 is Four Adjustable Voltage Monitoring Thresholds an undervoltage four-supply supervisor, and the ISL6132 is a 150ms STATUS/PGOOD Stability Time Delay two-voltage supervisor monitoring for undervoltage (UV) and Four Individual Open Drain STATUS Outputs overvoltage (OV) conditions. Guaranteed STATUS/PGOOD Valid to V <1V DD Both ICs feature four external resistor programmable voltage V and VMON Glitch Immunity DD monitoring (VMON) inputs, each with a related STATUS output V Lock-Out that individually reports the related monitor input condition. In DD addition, there is a Power-Good (PGOOD) signal that asserts 4mm X 4mm QFN Package high when the STATUS outputs are in their correct state. A - Compliant to JEDEC PUB95 MO-220 stability delay of approximately 160ms ensures that the QFN - Quad Flat No Leads - Package Outline monitored supply is stable before STATUS and PGOOD are - Near Chip Scale Package footprint, which improves PCB released to go high. The PGOOD and STATUS outputs are efficiency and has a thinner profile open-drain to allow ORing of the signals and interfacing to a Pb-Free (RoHS Compliant) wide range of logic levels. STATUS and PGOOD outputs are guaranteed to be valid with IC Applications bias lower than 1V, eliminating concern about STATUS and Multivoltage DSPs and Processors PGOOD outputs during IC bias up and down. VMON inputs are P Voltage Monitoring designed to ignore momentary transients on the monitored supplies.

Pin Descriptions PIN 6131 6132 PIN NAME FUNCTION DESCRIPTION 23 23 V Bias IC from nominal 1.5V to 5V DD 10 10 GND IC ground 20 NA VMON A On the ISL6131, these inputs provide a programmable UV threshold referenced to an internal 0.633V. The related STATUS output asserts when the related input > internal reference voltage. 12 NA VMON B On the ISL6132, these inputs provide a programmable UV and OV threshold referenced to an internal 0.633V reference. In the AB pair, VMON A is the UV input, and VMON B is the OV input. In the CD pair, VMON C is the UV 17 NA VMON C input, and VMON D is the OV input. 14 NA VMON D These inputs have a 30s glitch filter to prevent PGOOD reset caused by a transient. NA 12 OVMON 1 NA 20 UVMON 1 NA 17 UVMON 2 NA 14 OVMON 2 24 24 PGOOD On the ISL6131, PGOOD is the Boolean AND function of all four STATUS outputs. On the ISL6132, PGOOD is for the AB pair and signals high when the monitored voltage is within the specified window and the A and B STATUS output states are correct. This is an open-drain output and is to be pulled high to the appropriate level with an external resistor to a V DD maximum level. NA 9 PGOOD2 PGOOD2 is for the CD pair and signals high when the monitored voltage is within the specified window and when the C and D STATUS output states are correct. This is an open-drain output and is to be pulled high to the appropriate level with an external resistor to a V DD maximum level. FN9119 Rev 6.00 Page 2 of 15 February 11, 2014
