1 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 0.9 to 5 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. This 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.

MAX6763/MAX6764 Functional Diagram Detailed Description The MAX6754 MAX6764 are low-power window voltage detectors capable of monitoring undervoltage and overvoltage conditions on system power supplies. Whenever a monitored voltage falls below its undervoltage threshold or exceeds its overvoltage threshold, these devices assert their outputs to notify the system (see Functional Diagrams). The MAX6754/MAX6755/MAX6756 are single-voltage window detectors with internally fixed nominal voltage, externally adjustable set window, single reset undervoltage/ overvoltage output, and a manual reset input. The MAX6757/MAX6758/MAX6759 are single-voltage window detectors with internally set nominal voltage, externally adjustable set window, separate undervoltage/ overvoltage outputs, and manual reset input. The MAX6760/MAX6761/MAX6762 are dual-voltage window detectors with internally/externally set nominal voltages, externally adjustable set window, separate undervoltage/overvoltage outputs, manual reset input, and overvoltage latch functions. The MAX6763/MAX6764 are single adjustable window detectors with separate undervoltage/overvoltage outputs. The MAX6754 MAX6762 offer factory-fixed voltage thresholds for monitoring system voltages from 0.9 to 5. The MAX6754 MAX6762 include a SET function to select the window voltage to ±5%, ±10%, or ±15%. The MAX6763/MAX6764 allow for externally adjustable upper U O and lower voltage thresholds to be set externally (down to 0.5). The MAX6754 MAX6762 are available with two timing options (20μs propagation delay or 100ms minimum reset timeout). Supply oltages is the power-supply input and the monitored voltage of the MAX6754 MAX6762. These devices feature a factory-trimmed and 2 divider that sets the nominal input range (see Table 1 and Table 2). for the MAX6763/MAX6764 is the power supply of the device and not the monitored voltage.

Setting the Adjustable Nominal oltage Threshold The MAX6760/MAX6761/MAX6762 (versions with suffixes LA, TA, RA, ZA, WA, and AA) offer adjustable nominal voltage threshold to monitor 2. Use an external voltage-divider to set the voltage at 2 to Configure SET to select a monitor window of ±5%, ±10%, or ±15% (see Figure 5).

Drive OLATCH high to latch the overvoltage output for any or 2 overvoltage condition. Drive OLATCH low to clear the latch after overvoltage conditions have been removed. The latch is transparent when OLATCH is connected to. OLATCH is a high impedance input. Use external pullup or pulldown.
