LTC2913 Dual UV/OV Voltage Monitor FEATURES DESCRIPTION n Monitors Two Voltages Simultaneously The LTC 2913 is a dual input voltage monitor intended for n Adjustable UV and OV Trip Values multiple voltages in a variety of applications. Dual inputs for n Guaranteed Threshold Accuracy: 1.5% each voltage allow monitoring two separate undervoltage n Input Glitch Rejection (UV) conditions and two separate overvoltage (OV) n Adjustable Reset Timeout with Disable conditions. All monitors share a common undervoltage n 44A Quiescent Current output and a common overvoltage output. The LTC2913-1 n Open-Drain OV and UV Outputs has latching capability for the overvoltage output. The n Guaranteed OV and UV for V 1V LTC2913- 2 has functionality to disable both the overvoltage CC n Available in 10-Lead MSOP and (3mm 3mm) and undervoltage outputs. DFN Packages Glitch ltering ensures reliable reset operation without false or noisy triggering. APPLICATIONS The LTC2913 provides a precise, versatile, space-con- scious, micropower solution for voltage monitoring. n Desktop and Notebook Computers L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation. n Network Servers All other trademarks are the property of their respective owners. n Core, I/O Voltage Monitors TYPICAL APPLICATION Dual OV/UV Supply Monitor Typical Transient Duration vs Comparator Overdrive 5V 700 POWER 3.3V SUPPLIES 600 0.1F 500 RESET OCCURS ABOVE CURVE 400 44.2k V CC SYSTEM VH1 300 LTC2913-1 1k 27.4k VL1 OV 200 VH2 UV V = 6V CC 4.53k 1k 100 V = 2.3V VL2 LATCH CC 0 GND TMR 4.53k 0.1 1 10 100 2913 TA01a 22nF COMPARATOR OVERDRIVE PAST THRESHOLD (%) TIMEOUT = 200ms 2913 TA01b 2913fb 1 TYPICAL TRANSIENT DURATION (s)LTC2913 ABSOLUTE MAXIMUM RATINGS (Notes 1, 2) Terminal Voltages Operating Temperature Range V (Note 3) ............................................. 0.3V to 6V LTC2913C ................................................ 0C to 70C CC OV, UV ................................................... 0.3V to 16V LTC2913I.............................................. 40C to 85C TMR ..........................................0.3V to (V + 0.3V) LTC2913H .......................................... 40C to 125C CC VHn, VLn, LATCH, DIS .......................... 0.3V to 7.5V Storage Temperature Range ................... 65C to 150C Terminal Currents Lead Temperature (Soldering, 10 sec) I ..................................................................+10mA MSOP ...............................................................300C VCC I , I ............................................................... 10mA UV OV PACKAGE/ORDER INFORMATION TOP VIEW TOP VIEW VH1 1 10 V CC VH1 1 10 V CC VL1 2 9 TMR VL1 2 9 TMR 11 VH2 3 8 LATCH VH2 3 8 LATCH VL2 4 7 UV VL2 4 7 UV GND 5 6 OV GND 5 6 OV MS PACKAGE 10-LEAD PLASTIC MSOP DD PACKAGE T = 150C, = 120C/W 10-LEAD (3mm 3mm) PLASTIC DFN JMAX JA T = 150C, = 43C/W JMAX JA EXPOSED PAD (PIN 11) PCB GND CONNECTION OPTIONAL ORDER PART NUMBER MS PART MARKING* ORDER PART NUMBER DD PART MARKING* LTC2913CMS-1 LTCKK LTC2913CDD-1 LCKN LTC2913IMS-1 LTCKK LTC2913IDD-1 LCKN LTC2913HMS-1 LTCKK LTC2913HDD-1 LCKN TOP VIEW TOP VIEW 10 V VH1 1 CC VH1 1 10 V CC VL1 2 9 TMR VL1 2 9 TMR 11 VH2 3 8 DIS VH2 3 8 DIS VL2 4 7 UV VL2 4 7 UV GND 5 6 OV GND 5 6 OV MS PACKAGE 10-LEAD PLASTIC MSOP DD PACKAGE T = 150C, = 120C/W 10-LEAD (3mm 3mm) PLASTIC DFN JMAX JA T = 150C, = 43C/W JMAX JA EXPOSED PAD (PIN 11) PCB GND CONNECTION OPTIONAL ORDER PART NUMBER MS PART MARKING* ORDER PART NUMBER DD PART MARKING* LTC2913CMS-2 LTCKM LTC2913CDD-2 LCKP LTC2913IMS-2 LTCKM LTC2913IDD-2 LCKP LTC2913HMS-2 LTCKM LTC2913HDD-2 LCKP Order Options Tape and Reel: Add TR Lead Free: Add PBF Lead Free Tape and Reel: Add TRPBF Lead Free Part Marking:
