Application Field

The PS8A0026PEX is suitable for use in a variety of portable consumer electronics applications including digital cameras, portable media players, gaming consoles and other handheld devices. This device can be used for a variety of batteries including lithium-ion and lead acid batteries. It can also be used in applications such as motor drives, portable medical devices, smart meters, energy storage and green energy systems.

Working Principle

The PS8A0026PEX is a multi-mode charging controller device. It is capable of automatically switching between charging, discharging and idle modes, depending on the battery type and voltage. The device utilizes a 3-step charging algorithm, which includes bulk charging phase, constant voltage phase, and trickle charging phase. This device also features overvoltage protection and overcurrent protection, as well as reverse current protection.In the bulk charging phase, the charging current is supplied at a maximum rate until the battery reaches a designated voltage. In the constant voltage phase, the controller maintains the battery at a constant voltage, which is the setpoint voltage. In the trickle charging phase, the charging current is reduced to a lower rate for a specified period of time.The PS8A0026PEX also has a programmable current limit parameter which enables the user to limit the maximum charging current of the battery. The current limit can be programmed from 0.1A to 3.0A. The PS8A0026PEX also features fold-back current protection, which protects the battery from overcurrent or short circuit. The device also has reverse current protection which is used to prevent the battery from discharging the power system when the device is not in use.

Conclusion

The PS8A0026PEX is a low power, low voltage multi-mode charging controller designed for lithium-ion and lead acid batteries used in portable devices. It is a power management integrated circuit (PMIC) chip manufactured by ROHM Semiconductor, offering a wide range of features including low quiescent current, high ESD protection grade, wide operating temperature range, high output voltage accuracy, low voltage operation and current protection. The PS8A0026PEX is suitable for use in a variety of portable consumer electronics applications as well as motor drives, energy storage and green energy systems.
