Description
The FT7521 is a timer for resetting a mobile device where long reset times are needed. The long delay helps avoid unintended resets caused by accidental key presses. It has a fixed delay of 7.5 ±20% seconds. The DSR pin enables Test Mode operation by immediately forcing /RST1 LOW for factory testing. The FT7521 has one input for single-button resetting capability. The device has a single open-drain output with 0.5 mA pull-down drive. FT7521 draws minimal ICC current when inactive and functions over a power supply range of 1.65 V to 5.0 V.

HVishay Foil Resistors Notes:1.Maximum is 1.0 % A.Q.L. standard for all specifications except TCR. (For TCR information, see notes 2 and 3.)2.Maximum TCR applies to the 3 σ (sigma) limit or 99.73 % of a production lot. (Measured end-to-end with wiper off the element.)3.Measurements of TCR through the wiper are influenced more by setting stability and the percentage of the total resistance in use (at the wiper) than by fundamental resistance change due to temperature alone. The parameter shown in Table 2 is a 2 s distribution typifying the behavior of the device when used with 40% or more of the total resistance in use.4.Derated linearly for full power at + 85 °C to zero (0) W at +150°C.See Figure 2 on previous page.5.Independent of resistance value. 3 W maximum available on special request.6.All ΔR’s are measured to the tolerance specified + 0.01 Ω.7.Whichever is greater.Special Available Options:Special markingBurn-in and screening operations.VISHAY TRIMMERS ARE INSPECTED100 % for:•Short-time overload(6.25 x rated power for 5 s on; and for 30 s off - 3 cycles)•Immersion•Resistance tolerance check •End resistance •Visual-mechanical•Dynamic tests for continuity, CRV By sample for:•TCR •DWVTABLE 5 - COMPARISONMIL-PRF-39035/3 CHARACTERISTIC H 6)MODEL 1240 MAXIMUM TEST GROUP I ConditioningContact resistance variation - CRV (noise)Immersion± 1.0 %± 3.0 % or 3 Ω7)No continuous stream of bubbles± 0.5 %3 Ω typical, 10 Ω maximum No continuous stream of bubbles TEST GROUP I aVisual and mechanicalActual effective electrical travel End resistanceDielectric withstanding voltage - DWV (atmospheric and barometric pressure)Insulation resistance Shaft torque Thermal shock Setting stability No failures 10 to 25 turns 2 % or 2 Ω7)Per MIL-STD-202, methods 301 and 105≥ 1000 M Ω3 oz. in. maximum± 1.0 %± 1.0 %No failures 21 ± 2 turns2 Ω for values ≤ 1 k Ω;5 Ω for values ≥ 2 k Ω;Per MIL-STD-202, methods 301 and 105> 1000 M Ω3 oz. in. maximum± 0.5 %± 0.5 %TEST GROUP II SolderabilityPer MIL-STD-202, method 208Per MIL-STD-202, method 208TEST GROUP IIIResistance temperature characteristic - TCR Moisture resistanceContact resistance variation - CRV (noise)± 0.005 % (± 50 ppm/°C)± 1.0 %3.0 % or 3 Ω7)± 0.001 % (± 10 ppm/°C)± 0.5 %3 Ω typical, 10 Ω maximum TEST GROUP IV Settability ShockSetting stability VibrationSetting stabilityContact resistance variation - CRV (noise)Salt spray± 1.0 %± 1.0 %± 1.0 %± 1.0 %± 1.0 %3.0 % or 3 Ω7)No corrosion ± 0.1 %± 0.5 %± 0.5 %± 0.5 %± 0.5 %3 Ω typical, 10 Ω maximumNo corrosion TEST GROUP V Solder heatLow-temperature operation Setting stabilityLow-temperature storage High-temperature exposure Setting stabilityContact resistance variation - CRV (noise)Integrity of shaft± 1.0 %± 1.0 %± 2.0 %± 1.0 %± 3.0 %± 2.0 %3 % or 3 Ω7)No loosening or breakage± 0.1 %± 0.5 %± 0.5 %± 0.5 %± 0.5 %± 0.5 %3 Ω typical, 10 Ω maximum No loosening or breakage TEST GROUP VIRotational life (200 cycles)Contact resistance variation - CRV (noise)T erminal strength ± 2.0 %3 % or 3 Ω7)2 lbs.± 2.0 %3 Ω typical, 10 Ω maximum2 lbs.TEST GROUP VIILife (2000 h) at + 85 °C Life (10000 h) at + 85 °C ± 3.0 %± 5.0 %± 0.1 % typical, ± 1.0 % maximum ± 0.1 % typical, ± 1.0 % maximumTEST GROUP VIII Solvent resistance No failuresNo failures1240Vishay Foil ResistorsBulk Metal ® Foil Technology Precision Trimming Potentiometers, 1/4 Inch Square, RJ26 Style, Designed to Meet or Exceed the Requirements of MIL-PRF-39035, Char.
