ABLIC S-1410I45-K8T2U4

The S-1410/1411 series is a programmable watchdog timer developed using CMOS technology, featuring a low current consumption of 3.8 μA (typical). This series incorporates a reset function and a low-voltage detection function. The series offers a range of features, including detection voltage accuracy, input voltage, hysteresis width, and multiple operating modes. The detection voltage range spans from 2.0 V to 5.0 V in 0.1 V steps, with an accuracy of ±1.5%. The input voltage range is 0.9 V to 6.0 V. The hysteresis width is 5% (typical). Current consumption during watchdog timer operation is 3.8 μA (typical). For a CPOR capacitor of 2200 pF, the reset timeout period is 14.5 ms (typical), while for a CWDT capacitor of 470 pF, the watchdog timeout period is 24.6 ms (typical). Watchdog operation can be switched between enabled and disabled, with a watchdog operating voltage range of 2.5 V to 6.0 V. The watchdog mode can be switched between timeout mode and window mode, with the S-1411 series fixed in window mode. The watchdog input edge can be selected as rising edge, falling edge, or both. Product type is also selectable: the S-1410 series features a W/T pin (output: WDO pin), while the S-1411 series has no W/T pin (outputs: RST pin, WDO pin). The operating temperature range is -40°C to +105°C. The products are lead-free (Sn 100%) and halogen-free.
