PMIC - Supervisors

The MCP1316T-46BE/OT is a protection device manufactured by Microchip Technology, a world leading independent semiconductor company. It is an under-voltage dual supervisory circuit, integrated with over-voltage, active-low-level reset and comparator functions. This device is designed specifically to provide system reliability and protection against over-voltage and under-voltage conditions which could possibly damage modern electronic systems and equipment.

Applications of MCP1316T-46BE/OT

The MCP1316T-46BE/OT can be used in a wide variety of markets, including but not limited to industrial, computer peripheral, automotive, and consumer electronics. The device can be used as an overvoltage protector for computer peripheral applications such as USB ports, autonomous battery protection for automotive, and over-current protection for tablets and iPhones. It can also be used for a variety of other industrial applications such as controlling and monitoring the energy consumption of the system, temperature control, and protection of communications systems.

Working Principle of MCP1316T-46BE/OT

The MCP1316T-46BE/OT works as a supervisory circuit that monitors power management and performance of the system. The set voltage window numbers are compared against the TTL and CMOS threshold internally, with the result being evaluated against the reference voltage. When the voltage exceeds the TTL or CMOS thresholds, an active-low reset is generated and the device output logic is changed. With the reset, all operations are stopped until the reset logic is restored.

The device also functions as an under-voltage detector and will reset when the voltage drops below a preset threshold. This feature is useful in controlling shut down in the event of a sudden power failure, as the device will be immediately triggered to shut down the system, thus preventing damage and system malfunctions.

The device also has an over-voltage protection function which will instantly shut down the system when a high voltage is detected. The reset level is adjustable by the user through changing the PAR pin voltage and this allows the user to select the preset voltage level for under and over voltage protection.

Conclusion

The MCP1316T-46BE/OT is an excellent protection device and offers a cost-effective way to secure and protect any system and circuit design. The device combines all the necessary over-voltage and under-voltage protection, active-low reset and comparator features, making it an ideal choice for a wide range of industrial, consumer and automotive applications.
