ABLIC S-1410G30-K8T2U4

The S-1410/1411 series are watchdog timer ICs developed using CMOS technology, capable of operating at a low current consumption of 3.8 μA (typ.). This series features both reset function and voltage detection function. Series characteristics include detection voltage, detection voltage accuracy, input voltage, hysteresis width, current consumption during watchdog timer operation, reset timeout period, and watchdog timeout period. Watchdog operation is switchable and can be configured for either timeout mode or window mode. The watchdog input edge is selectable, and the product type is also selectable. The operating temperature range is -40°C to +105°C, and the products are lead-free (Sn 100%) and halogen-free. This series is suitable for power supply monitoring and system monitoring in microcontroller-based devices. Available package types include TMSOP-8 and HSNT-8(2030).

• Detection voltage: 2.0 V to 5.0 V, selectable in 0.1 V steps
• Detection voltage accuracy: ±1.5%
• Input voltage: VDD = 0.9 V to 6.0 V
• Hysteresis width: 5%
• Current consumption during watchdog timer operation: typical 3.8 μA
