Introduction to BQ24150AYFFT

The BQ24150AYFFT is a Single-cell, high efficiency, constant current/constant voltage linear charger that is designed for charging single-cell Li-ion and Li-pol cells. It has a wide input voltage range from 4V to 16V and can be used with various outputs and voltages. The device includes a low variable frequency oscillator, a low quiescent current current source and P-channel MOSFET. The maximum charging current is 1A, while the typical charging current is 0.5A.

Features of BQ24150AYFFT

The BQ24150AYFFT is a single-cell, high efficiency, linear battery charger IC with a wide input voltage range of 4V to 16V. It features current-limit protection, low quiescent current, adjustable features, and low ripple. The device also offers built-in overcharge protection, reverse battery protection, and thermal shutdown. Additionally, the device supports both constant-current/constant-voltage charging and manual cutoff when desired.

BQ24150AYFFT Application Field and Working Principle

The BQ24150AYFFT is ideal for applications such as smartphones, tablets, notebook computers, and other mobile devices that require a reliable, high-efficiency, single-cell linear charger. The device is also suitable for use in automotive, fuel-cell and other applications that need charging at constant current and constant voltage levels.The device works by compressing and amplifying an input signal to regulate its output current or voltage. It features P-channel power MOSFETs, a low ripple current source,and two current-sensing pinouts. The device includes an adjustable clock generator, biasing network, and a linear regulator. The device also has a temperature sensing pin for temperature-dependent charging. When the device is connected to a power supply, the voltage is sensed and converted into a digital representation by the low-variable frequency oscillator (LVFO). The adjusted current from the LVFO is filtered by a low-ripple current source, and then sent to the linear regulator. The linear regulator then amplifies the current and converts it into an output voltage, which is then delivered to the battery.

Technical Specifications of BQ24150AYFFT

The BQ24150AYFFT is a single-cell, high efficiency, linear battery charger IC with a wide input voltage range of 4V to 16V. Its features include adjustable features, current-limit protection, low quiescent current, reverse battery protection, and low ripple current. The maximum charging current is 1A, while the typical charging current is 0.5A. The device can provide up to 95% efficiency, has a nominal operating temperature range of -20°C to +85°C, and has a dimension of 3.00mm x 3.20mm x 0.4mm.

Conclusion

The BQ24150AYFFT is a high efficiency single-cell linear battery charger IC that is designed for applications such as smartphones, tablets, notebooks computers and other mobile devices. It is a low-ripple current source with an adjustable clock generator and low variable frequency oscillator. The device offers current-limit protection, low quiescent current and reverse battery protection, and can provide up to 95% efficiency.
