MAX6754MAX6764 19-3075 Rev 4 1/11 Low-Power, Single/Dual-Voltage Window Detectors General Description Features The MAX6754MAX6764 low-power window detectors Single- or Dual-Supply Voltage Monitors monitor undervoltage/overvoltage conditions on system Factory-Trimmed Window Threshold Options for power supplies. These devices assert when the moni- 5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V tored voltage is under the undervoltage and/or over the Supplies overvoltage thresholds. The MAX6754MAX6759/MAX6763/MAX6764 monitor a Externally Adjustable Window Monitoring Options single voltage. The MAX6760/MAX6761/MAX6762 for Supplies Down to 0.5V monitor dual-voltage systems. The MAX6754/MAX6755/ Selectable Window Threshold Options (5%, MAX6756 provide a single undervoltage/overvoltage 10%, 15%) output and the MAX6757MAX6764 provide indepen- dent undervoltage and overvoltage outputs. The out- Single (Combined UV/OV) or Dual (Separate UV puts are available in push-pull or open-drain and OV) Outputs configurations. 20s (typ) or 100ms (min) Timeout Period Options The MAX6754MAX6762 offer factory-fixed voltage (MAX6754MAX6762) thresholds for monitoring system voltages from 0.9V to Manual Reset Input (MAX6754MAX6762) 5V with a selectable 5%, 10%, or 15% window volt- age. The MAX6763/MAX6764 allow for externally Latched Overvoltage Output Function adjustable thresholds. The MAX6754MAX6762 are (MAX6760/MAX6761/MAX6762) available in two delay timing options (20s, typ or Immune to Short Voltage Transients 100ms, min). The MAX6760/MAX6761/MAX6762 also include a latched overvoltage output function and the Low 10A Supply Current MAX6754MAX6762 include a manual reset input. Low-Voltage Operation (Outputs Valid for V CC The family of products is available in small SOT23 and Down to 1V) TDFN packages and is specified over the extended temperature range of -40C to +125C. -40C to +125C Operating Temperature Range Small SOT23 and TDFN Packages Applications Telecommunications Power Metering Ordering Information Networking DC-DC Converter PART* TEMP RANGE PIN-PACKAGE Modules Computers/Servers MAX6754UK D -T -40C to +125C 5 SOT23-5 Automotive Data Storage MAX6755UK D -T -40C to +125C 5 SOT23-5 MAX6756UK D -T -40C to +125C 5 SOT23-5 MAX6757UT D -T -40C to +125C 6 SOT23-6 MAX6758UT D -T -40C to +125C 6 SOT23-6 Typical Application Circuit *Insert the threshold level suffixes for V and V (Tables 1 CC CC2 and 2) after UK, UT, or TA. For the MAX6754MAX6759, insert V CC only the V threshold suffix after the UK or UT. Insert the reset CC timeout delay (Table 3) after D to complete the part number. For P example, the MAX6760TALTD3-T provides a V threshold of CC MAX6757 5V, a V threshold of 3.3V, and a 100ms minimum reset time- CC2 V SET CC out 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 GND OV NMI versions have an order increment requirement of 10,000 pieces. Contact factory for availability. Devices are available in both leaded and lead-free packaging. MR UV RESET Specify lead-free by replacing -T with +T when ordering. Ordering Information continued at end of data sheet. Pin Configurations appear at end of data sheet.
