ON Semiconductor NCV303LSN24T1G Voltage Detector

The ON Semiconductor NCV303LSN24T1G is a precision micro-power voltage detector crafted for the stringent requirements of automotive and industrial applications. This device is designed to monitor the voltage level of batteries and other power supplies, ensuring that systems operate within their specified voltage ranges, which is critical for maintaining optimal performance and reliability.

The NCV303LSN24T1G is characterized by its low supply current, making it an ideal choice for use in power-sensitive applications. It features a fixed threshold voltage of 2.4V, which offers a precise monitoring solution for 3V power rails commonly found in electronic systems. When the input voltage drops below the 2.4V threshold, the output of the detector transitions from high to low, signaling that the voltage level is outside of the acceptable range.

This voltage detector is housed in a compact SOT-23 package, which is highly appreciated for its space-saving benefits, especially in applications where PCB real estate is at a premium. The small footprint of the NCV303LSN24T1G does not compromise its performance or reliability, making it an excellent choice for portable and compact electronic assemblies.

Key features of the NCV303LSN24T1G include:

• Operating Voltage Range: 1.0V to 5.5V
• Low Supply Current: Typically 0.8 µA
• High Accuracy: ±2.5% Threshold Tolerance Over Temperature
• Fast Response Time
• Open Drain Output
• Built-in Hysteresis: Helps to prevent false triggering from transient voltages
• Temperature Range: -40°C to +125°C
• Automotive Grade: Qualified for stringent automotive applications as per AEC-Q100 standards

Applications for the NCV303LSN24T1G are diverse, ranging from automotive systems, such as engine control units and infotainment systems, to industrial equipment, including factory automation and power management systems. The device's robustness and precision also make it suitable for battery-powered devices, where monitoring the battery level is crucial to the device's operation and longevity.

With its combination of low power consumption, high accuracy, and compact packaging, the NCV303LSN24T1G from ON Semiconductor is an essential component for designers looking to incorporate reliable voltage detection capabilities into their automotive or industrial electronic designs.
