The NCV303LSN49T1G is a voltage detector designed for use in microprocessor-based systems, particularly where low power consumption is critical. It features a high accuracy undervoltage detection threshold with a typical accuracy of 2.0% and a programmable time delay generator to prevent erratic resets. The device operates within a wide voltage range of 0.8 V to 10 V and has a quiescent current of only 0.5 µA, making it suitable for battery-powered applications. This component is AEC-Q100 qualified, indicating its reliability for automotive applications, and is compliant with RoHS standards. The NCV303LSN49T1G has an open-drain output with an active low reset, and it is specified to operate over a temperature range of -40°C to +125°C. Typical applications include microprocessor reset control, low battery detection, and power fail indication. The device is packaged in a TSOP-5 format, facilitating integration into compact designs.
