Power management integrated circuits (PMICs) are electronic circuits used to manage power generated, supplied and used by the system or device. This power management, or the ability to control the flow and regulation of the power, is important to maintain a correct device operation, to reduce system cost, and to extend the battery life of the application. One type of PMIC is a supervisor IC, which is a power circuit used to prevent system failures and to protect other on-board components from damage due to reverse-polarity and over/under voltage conditions.

The S-1003NB30I-I6T1U Power Failure Detector IC is a device that falls into the type of PMIC known as supervisors. S-1003NB30I-I6T1U is a supervisor IC designed to monitor, detect, and report system power supply conditions in +1.8V -5.5V systems. The S-1003NB30I-I6T1U Power Failure Detector IC includes a voltage supervisor and supply voltage detector, as well as advanced features such as digital filtration, a peak detection circuit, and an adjustable reset/ output delay time.

The S-1003NB30I-I6T1U is typically used in systems such as smartphones, digital televisions, tablets, notebooks, display devices, and other portable devices. These devices must manage the power supply to ensure it is maintained at the right voltage. The S-1003NB30I-I6T1U\'s power supply detection circuit, operating at 1.8V -5.5V, monitors the supply voltage and when the voltage drops or rises beyond the preset lower and upper threshold limits the power fails signal is sent to the system. This ensures that the system is protected against over-/under-voltage and reverse polarity conditions, making the S-1003NB30I-I6T1U an ideal device for automotive, medical and industrial applications.

The S-1003NB30I-I6T1U includes three functional blocks: an input resistor divider used to set the desired monitor supply voltage threshold, a power monitor circuit, and a digital filter used to reduce noise and crosstalk noise that can cause false voltage measurements. The input resistor divider is used to adjust the upper and lower voltage thresholds. The power monitor circuit compares the preset voltage to the actual system voltage, triggering the power failure signal when the voltages differ by more than the predetermined margin. The digital filter is used to reduce any high frequency electrical noise that can affect the accuracy of the power failure signal.

The S-1003NB30I-I6T1U Power Failure Detector IC integrates advanced power monitoring functions and a state-of-the-art voltage detector to provide stability and reliability. This makes it ideal for applications requiring a high degree of precision in power monitoring and failure detection. The S-1003NB30I-I6T1U is designed to provide a power failure signal in less than 20μs and can accurately monitor power supply voltages in a range of +1.8V - 5.5V. The S-1003NB30I-I6T1U also includes a peak detector that can detect changes in voltage and trip the power failure signal. Additionally, it features adjustable reset/output delay time and a low-power shutdown mode for efficient power monitoring in low power systems.

The S-1003NB30I-I6T1U Power Failure Detector IC is a highly reliable and advanced supervisor IC for a wide range of applications requiring power failure detection. Its state-of-the-art features such as a digital filter, peak detector, adjustable reset/output delay, a low-power shutdown mode, and advanced power monitoring functions make it the ideal choice for many applications. With its ability to protect against over/under voltage and reverse polarity conditions, the S-1003NB30I-I6T1U is an ideal choice for automotive, medical and industrial applications that require precision power monitoring.
