The g ap between the two thresholds defines the allowed voltage range. As long as VDD stays inside this voltage window, the output stays inactive. If V DD drops below VTHlow, or rises above VTHhigh, the output gets active. When V DD enters into the allowed range, the output remains active for an additional 50 ms (typ.). This allows the system to stabilize before getting fully active. The lower thresho ld voltage may be obtained in different versions: 2.0 V to 6 V 2.4 V to 6 V 2.8 V to 6 V 3.5 V to 6 V 4.0 V to 6 V 4.5 V to 6 V Pin Assignment TO-92 View Flat Front V6310 1 2 3 VDD RES VSS or RES SOT-223 1) SOT-23 5L VSS 4 Applications All microprocessor applications where an automatic restart is required: n Computer electronics n White / Brown goods n Automotive electronics n Industrial electronics n Telecom systems n Hand-held systems NC VSS NC 3 2 1 V6310 1 2 3 4 V6310 5 RES or VSS RES 1) VDD RES or RES VDD Fig. 2 On request 1 R V6310 Absolute Maximum Ratings Parameter Voltage at VDD to VSS Min. voltage at RES or RES Max. voltage at RES or RES Storage temperature range Symbol VDD Vmin Vmax TSTO Conditions -0.3V to+10 V VSS - 0.3 V VDD + 0.3 V -65O to +150 OC Table 1 Stresses above these listed maximum ratings may cause permanent damage to the device. Exposure beyond specified operating conditions may affect device reliability or cause malfunction. Handling Procedures This device has built-in protection against high static voltages or electric fields; however, anti-static precautions must be taken as for any other CMOS component. Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the supply voltage range.
