Working Principle

The SM72295MA/NOPB provides a complete power management solution for applications requiring low quiescent current and transient response. The solution integrates high efficiency, over-voltage protection, over-temperature protection, short-circuit protection, and load-active protection into a single IC.

The device integrates a high-voltage unregulated DC-DC converter, which provides an efficient and flexible linear regulator solution. The DC-DC converter utilizes Switch-Mode technology which significantly reduces power consumption and extends battery life. The device also integrates an analog control loop which provides excellent transient response and dynamic regulation performance. The device also integrates an over-voltage protection circuit to ensure that it does not over-regulate and cause damage to the load.

To protect the device from over-temperature and short-circuit conditions, the SM72295MA/NOPB PMIC integrates a thermal monitoring circuit. The thermal monitoring circuit is used to detect over-temperature conditions, and if an over-temperature condition is detected, the device will automatically shut-down to protect itself. Additionally, the device integrates a load-active protection circuit which can be used to watermark large current surges in order to protect the power supply from damage.

Conclusion

The SM72295MA/NOPB PMIC family is designed to provide a comprehensive and energy efficient power management solution for appliance and consumer electronic products. The solution integrates a high-voltage DC-DC converter, analog regulation, over-voltage and over-temperature protection, and a load-active protection circuit into a single IC. The device is expected to extend battery life and eliminate the need for multiple components, thereby reducing the system footprints and complexity.
