Power Management Integrated Circuit (PMIC) is an important component in any electronic device. It provides the necessary power management features required to power a system or application. PMICs are designed to convert source power into various voltages and currents that are needed in a device or application. PMICs are widely used in a variety of applications, including portable electronic devices, home appliances and industrial equipment. Supervisors are a specific type of PMICs that are utilized for protecting the system from faulty power-on sequences and outages.

The CAT1640WI-45-T3 is an advanced Pre-Programmable PMIC supervisor that offers a high level of protection, including input under voltage protection, regulated output voltage protection and output over voltage protection. It has a built-in diagnostic and fault detection features, with selectable reset thresholds. The CAT1640WI-45-T3 is designed for use in extremely demanding conditions, making it an ideal choice for applications such as factory automation, industrial computers and other harsh environment applications.

The CAT1640WI-45-T3 has several features that make it a great choice for its application field. It has a very low power consumption of just 3 mW, which makes it well suited for battery powered applications. It also has an operating temperature range of -40 °C to 85°C and a storage temperature range of -65°C to 150°C. It is compatible with industry-standard Power Management Integrated Circuits (PMICs) and has a 3V to 20V range for output voltages and a frequency range of 320 - 1000 kHz.

The CAT1640WI-45-T3 also has a programmable reset time-out delay and offers sealed and hermetic package options for improved environmental protection. The supervisor has an integrated EMI filter that helps reduce the amount of EMI radiation generated and a low shutdown current that reduces the current drawn during shutdown. Additionally, the supervisor supports a wide range of voltages and is qualified to AEC-Q100 standards.

The working principle of the CAT1640WI-45-T3 is relatively straightforward. It works by monitoring the input power supply to detect any anomalies, such as input undervoltage, voltage oscillation or over-current. If any of these conditions is detected, the supervisor will shut down the system immediately to prevent any damage or system failure. The supervisor also monitors the output voltage level to ensure that it is within the programmed voltage range and will shut down the system if it is outside this range.

The CAT1640WI-45-T3 Pre-Programmable PMIC supervisor is a great choice for applications that require reliable and robust power management solutions. Its low power consumption and wide temperature range make it the ideal choice for battery powered applications. It also features an integrated EMI filter and various protection features, making it a great choice for harsh environment applications, such as factory automation and industrial computers.
