MAX8724ETI+T

PMIC (Power Management Integrated Circuit) is a widely used component in the electronics industry. MAX8724ETI+T is a high performance PMIC used to control and provide power to portable electronic devices. It is designed to provide a cost-effective solution for power supply in battery charger applications.

The MAX8724ETI+T includes an input current fader, an adjustable current limit, and a programmable feedback voltage. It uses an external voltage reference to set the input current, as well as the output voltage, to achieve maximum efficiency. It also features an adjustable power-off delay timer to allow for an orderly system shutdown.

The MAX8724ETI+T is ideal for portable applications such as cell phone battery chargers, digital cameras, MP3 players, and other small devices. It is well-suited for high-efficiency, low-current applications, but can also be used in medium- and high-current applications. The device can be used as a single power source, or in conjunction with other power management ICs.

The working principle of the MAX8724ETI+T is simple. The device is configured as a flyback converter, meaning that it uses an inductor and a capacitor to convert the input voltage into an output voltage. The output voltage is then regulated by an on-chip voltage regulator. The current is set by an adjustable current limit, which is set via the external voltage reference. The output voltage is monitored by the internal feedback circuit, which then adjusts the current accordingly to maintain the required voltage set point.

The MAX8724ETI+T can provide power to a variety of devices with a wide range of operating voltages. It is highly efficient and has a wide operating temperature range from -40°C to +85°C. The device includes on-chip temperature and voltage protection and a fault-indication pin to monitor current and power-supply status.

Overall, the MAX8724ETI+T is a high-performance, cost-effective and reliable solution for battery charger applications. It is a versatile device that is suitable for a wide range of applications and is designed to meet the demands of portable electronic devices. With its adjustable current limit, programmable feedback voltage, and wide operating temperature range, the MAX8724ETI+T is an excellent choice for powering portable electronic devices.
