The NCP304HSQ47T1G is a cost-effective, precision micropower supervisor ideal for monitoring power supply sequencers, charging systems, and portable applications. It features a precision and ultra-low power consumption to enable it to monitor system voltage levels continuously over a wide range of environmental conditions. This application supervisor is popular due to its wide range of features, including robust 15-ns (typical) undervoltage lockout time and a wide range of operating voltages. It is compact in size, making it suitable for use in confined spaces.

The NCP304HSQ47T1G is powered by a precision 2.5-V to 6.5-V supply voltage to enable monitoring of multiple voltage levels. It is offered in 2 varieties: active-low reset or push-pull reset. This micropower IC supervisor employs a supervisory circuit to ensure reliable system performance by monitoring the system’s DC power systems. It also has three comparators that can detect system power supply undervoltage or overvoltage, as well as reset and warning thresholds. The NCP304HSQ47T1G can also detect instances when power supply voltage is outside the allowable range, thus preventing malfunctions.

The NCP304HSQ47T1G is a precision micropower supervisor and finds a wide range of applications in industrial and telecommunications systems, battery-powered devices, and low power control systems. For example, the device can be used for monitoring industrial probes, in telecommunications systems to monitor the health of battery-dependent systems such as satellite systems, and in small power control systems to monitor voltage levels from multiple sources.

In terms of its working principle, the NCP304HSQ47T1G uses three voltage comparators to monitor the input voltage and send out a logic-low reset voltage when the voltage is above or below the output threshold levels. This logic-low reset will then activate the reset functions on any circuits or logic devices connected to the NCP304HSQ47T1G. The micro-power supervisor also has two additional voltage comparators which can be used to generate either a logic-low warning voltage or a logic-high warning voltage when the input voltage is at or outside the warning threshold levels. This warning voltage can then activate pre-defined warning functions.

Overall, the NCP304HSQ47T1G is a cost-effective and precision micropower supervisor designed for monitoring power supply sequencers, charging systems, and portable applications. It features robust 15-ns (typical) undervoltage lockout time, a wide range of operating voltages, and a low supply voltage for monitoring multiple voltage levels. Its precision micropower design makes it suitable for use in a wide range of applications from industrial and telecommunications systems, to battery-dependent devices, and small power control systems. The device also employs a supervisory circuit to ensure reliable system performance and three voltage comparators to detect system power supply undervoltage or overvoltage, reset and warning thresholds.
