19-3075; Rev 2; 4/04 www.DataSheet4U.com Low-Power, Single/Dual-Voltage Window Detectors General Description The MAX6754–MAX6764 low-power window detectors monitor undervoltage/overvoltage conditions on system power supplies. These devices assert when the monitored voltage is under the undervoltage and/or over the overvoltage thresholds. The MAX6754–MAX6759/MAX6763/MAX6764 monitor a single voltage. The MAX6760/MAX6761/MAX6762 monitor dual-voltage systems. The MAX6754/MAX6755/ MAX6756 provide a.

19-3075; Rev 2; 4/04 www.DataSheet4U.com Low-Power, Single/Dual-Voltage Window Detectors General Description The MAX6754–MAX6764 low-power window detectors monitor undervoltage/overvoltage conditions on system power supplies. These devices assert when the monitored voltage is under the undervoltage and/or over the overvoltage thresholds. The MAX6754–MAX6759/MAX6763/MAX6764 monitor a single voltage. The MAX6760/MAX6761/MAX6762 monitor dual-voltage systems. The MAX6754/MAX6755/ MAX6756 provide a single undervoltage/overvoltage output and the MAX6757–MAX6764 provide independent undervoltage and overvoltage outputs. The outputs are available in push-pull or open-drain configurations. The MAX6754–MAX6762 offer factory-fixed voltage thresholds for monitoring system voltages from 0.9V to 5V with a selectable ±5%, ±10%, or ±15% window voltage. The MAX6763/MAX6764 allow for externally adjustable thresholds. The MAX6754–MAX6762 are available in two delay timing options (20µs, typ or 100ms, min). The MAX6760/MAX6761/MAX6762 also include a latched overvoltage output function and the MAX6754–MAX6762 include a manual reset input. The family of products is available in small SOT23 and TDFN packages and is specified over the extended temperature range of -40°C to +125°C. Features ♦ Single- or Dual-Supply Voltage Monitors ♦ Factory-Trimmed Window Threshold Options for 5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V Supplies ♦ Externally Adjustable Window Monitoring Options for Supplies Down to 0.5V ♦ Selectable Window Threshold Options (±5%, ±10%, ±15%) ♦ Single (Combined UV/OV) or Dual (Separate UV and OV) Outputs ♦ 20µs (typ) or 100ms (min) Timeout Period Options (MAX6754–MAX6762) ♦ Manual Reset Input (MAX6754–MAX6762) ♦ Latched Overvoltage Output Function (MAX6760/MAX6761/MAX6762) ♦ Immune to Short Voltage Transients ♦ Low 10µA Supply Current ♦ Low-Voltage Operation (Outputs Valid for VCC Down to 1V) ♦ -40°C to +125°C Operating Temperature Range ♦ Small SOT23 and TDFN Packages MAX6754–MAX6764 Applications Telecommunications Networking Computers/Servers Data Storage Power Metering DC-DC Converter Modules Automotive Ordering Information PART* MAX6754UK_D_-T MAX6755UK_D_-T MAX6756UK_D_-T MAX6757UT_D_-T MAX6758UT_D_-T TEMP RANGE -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C PIN-PACKAGE 5 SOT23-5 5 SOT23-5 5 SOT23-5 6 SOT23-6 6 SOT23-6 Typical Application Circuit VCC µP MAX6757 VCC SET GND OV NMI *Note: Insert the threshold level suffixes for VCC and VCC2 (Tables 1 and 2) after UK, UT, or TA. For the MAX6754–MAX6759, insert only the VCC threshold suffix after the UK or UT. Insert the reset timeout delay (Table 3) after D to complete the part number. For example, the MAX6760TALTD3-T provides a VCC threshold of 5V, a VCC2 threshold of 3.3V, and a 100ms minimum reset timeout period. Sample stock is generally held on standard versions only (see the Standard Versions table). Standard versions have an order increment requirement of 2500 pieces. Nonstandard versions have an order increment requirement of 10,000 pieces. Contact factory for availability. Ordering Information continued at end of data sheet.
