FSA832L10X

PMIC - Battery Management

Modern technology platforms require power as an essential component and have an interface between the DC power supply and the device. Power Management ICs (PMICs) are the device which ensures balanced power management, which helps to regulate and limit power supply and ensure the device working efficiently and safely. PMICs, such as the FSA832L10X model, provide manageable power solutions to maintain the efficiency of the device.

Application Field

The FSA832L10X is an advanced power management integrated circuit (PMIC), which provides integrated power management with applications to power up, power down and reset autonomously. Other functions such as temperature sensings, voltage monitoring and low voltage reset are also integrated. This IC can be used in portable consumer electronics, cameras, USB DS, audio appliances and automated application control systems.

Working Principle

The FSA832L10X is mission specific to reduce the component count and speed up the design time. It also helps to reduce power consumption. The IC features various safety blocks, such as overvoltage lockout, over temperature protection, emergency shutdown, and reset system timer events, which helps to protect the device from damages. It also supports independent buck or Boost/SEPIC conversion, which helps to provide power switch design flexibility and allows many portable electronic devices to share the same platform.

The IC is integrated with two autonomous DC-DC buck converters, which help to reduce power consumption and can provide up to 8.5A total output. Both buck converters can be functions independently. It also has 3.3V and 5V LDO, which help to provide reference voltage for soft start and light load operation.

The FSA832L10X also offers low standby current for eco power functions, with average quiescent current of 1uA. This helps to reduce the device overall power consumption, allowing a longer time operation time, and enhancing power efficiency. Further, eFlex IPS ensures that larger inductor size can be used to limit the operating temperature, while still providing good power conversion efficiency.

Conclusion

The FSA832L10X is an advanced power management IC, featuring low quiescent current and ultra-low dropout voltage regulator, which enables the device to have a more efficient power source. Its various safety blocks and eFlex IPS technology protect the device from any potential damages, and its buck or boost/SEPIC functions provide design flexibility for many portable electronic devices.
