ON Semiconductor NCP308SN250T1G: Voltage Supervisor IC

The NCP308SN250T1G from ON Semiconductor is a high-performance Voltage Supervisor IC designed to monitor the power supply voltage levels in electronic systems. This device ensures that the voltage supplied to sensitive components remains within a safe operating range, protecting them from potential damage due to undesirable voltage conditions. It is particularly suitable for use in microprocessor-based systems where precise power monitoring is critical.

The NCP308SN250T1G offers a fixed threshold voltage of 2.50V, making it ideal for 2.5V-powered applications. It features a highly accurate threshold voltage with a tight tolerance, ensuring reliable operation even under varying conditions. The device has a low supply current, which makes it an energy-efficient choice for battery-operated devices.

One of the key features of the NCP308SN250T1G is its built-in hysteresis, which prevents false triggering and ensures stable operation by avoiding the on-off chattering near the threshold voltage. This hysteresis is particularly useful in environments with noisy signals where voltage levels may fluctuate rapidly.

The device is equipped with an active-low, open-drain reset output. This output remains asserted (low) until the monitored voltage exceeds the threshold, plus the hysteresis margin, ensuring that the system has stabilized before allowing it to resume operation. The reset delay time can be programmed externally via a capacitor to suit various system requirements.

The NCP308SN250T1G comes in a compact, space-saving 5-pin TSOP-5 package, making it an excellent choice for space-constrained applications. Its small footprint allows for easy integration into a wide range of electronic products, from portable devices to complex computing systems.

With its robust feature set, including over-temperature shutdown and glitch immunity, ON Semiconductor's NCP308SN250T1G Voltage Supervisor IC is a reliable solution for protecting sensitive electronic circuits from improper voltage levels, ensuring system stability and prolonging the lifespan of electronic components.

For designers and engineers looking for a dependable voltage monitoring solution, the NCP308SN250T1G offers the perfect blend of precision, reliability, and compactness to meet the stringent requirements of modern electronic systems.
