Additional Details

The S-1000N18-M5T1U features an open-drain output, which requires an external pull-up resistor. The hysteresis characteristic prevents chattering or oscillation of the output signal when the input voltage is near the detection threshold. This voltage detector's precise voltage detection and low power consumption make it ideal for portable devices and other applications where battery life is critical. The operating temperature range typically spans from -40°C to +85°C, making it suitable for use in harsh environments. The output voltage is usually equivalent to the supply voltage for a high output state, and near ground for a low output state.
