Power Management Integrated Circuits (PMICs) are an essential element in any electronics device, from the smallest portable devices to large industrial systems. These circuits provide voltage control and power management, allowing devices to be powered optimally, saving energy and reducing heat output.

The S-80843CLMC-B64T2G is a multi-function Supervisor IC from Renesas Electronics Corporation, effectively combining several individual components into one, reducing the size and complexity of a design. It falls under the PMIC - Supervisors category, and is specifically designed to monitor power supply voltages and detect irregularities, while also providing protections against faults and supporting timed reset functions. This allows material and labor costs to be reduced owing to the fact that fewer components are needed.

S-80843CLMC-B64T2G is suitable for almost any application that requires basic power supply supervisory functions. It is designed primarily for consumer, industrial, and telecommunication applications, and some of the applications that the chip can be used in include audio and video products, measuring and testing instruments, industrial controllers, micro-controllers, and telephone systems. The chip is also suitable for any application that requires reset or watchdog functions as well.

The S-80843CLMC-B64T2G is a multi-functional supervisor with integrated voltage monitoring, reset and power-saving functions. It is configured with the following features:

• Voltage monitoring functions help protecting circuits by monitoring the operation of up to 4 power-supply voltages.
• Fault and failure signals are detected and indicated and can be used to initiate corrective action.
• Time functions help reduce/extend circuits or operating power as necessary.
• Voltages can be monitored from 1V to 3.6V with adjustable trip levels.
• Time functions include single-shot and periodic timing for reset or shutdown purposes.
• A watchdog timer with an adjustable timeout period is also included.
• A power-saving signal is available to support power conservation.

The S-80843CLMC-B64T2G Supervisor IC is designed to be tolerant of fast changing power-supply transients. Its monitoring functions can detect voltage instability, under-voltage, over-voltage, and fluctuations. The signals generated can be used to reconfigure power supplies, activate power-saving features, initiate corrective action or shut down operations altogether if needed.

In addition, the chip includes a watchdog timer, which triggers a timeout if the host system fails to reset it within a predetermined period. This prevents system failure due to malfunctions, and helps to improve overall system reliability.

Finally, the chip is designed to support a power-saving signal. This signal can be used to reduce power consumption in applications that do not require high operating speed. Additionally, an On/Off feature is provided, which can be used to switch between power-saving and normal operation.

In summary, the S-80843CLMC-B64T2G PMIC Supervisor IC is a versatile, reliable and cost-effective solution for power supply monitoring and protection. It is compliant with both Industrial and RoHS standards and is available in a standard 28-pin MSOP package, making it ideal for use in a wide range of applications.
