A power management integrated circuit (PMIC) is a device that integrates multiple power device functions into a single Integrated Circuit (IC). PMICs are typically used in mobile devices such as smartphones, tablets and wearables, as well as other mobile applications. The AP2311AS-13 is a PMIC specifically designed for load drivers and power distribution switches applications.

Overview

The AP2311AS-13 is a high-performance, low-voltage power management IC (PMIC) designed for load drivers, power distribution switches and other applications. The device is available in an SSOP-20 package and features three channels, each of which can be independently enabled or disabled. The AP2311AS-13 features a wide input voltage range, low quiescent current, high-side current sensing, fault detection and a slew rate of 2A/μs.

• Slew rate of 2A/μs

Applications

The AP2311AS-13 is suitable for a wide range applications, including driving high-power LEDs, powering processors and other ICs, powering batteries and peripheral devices, as well as in battery-powered applications such as smartphones, tablets and wearables.

Working Principle

The AP2311AS-13 is a high-performance and low-voltage PMIC designed for load drivers and power distribution switches. The device integrates three independent channels, each of which can be independently enabled and disabled. The device also features a wide input voltage range, low quiescent current, high-side current sensing, fault detection and a slew rate of 2A/μs.

The AP2311AS-13 is designed to efficiently power and control low-voltage devices. The device features two main voltage regulating features – current limiting and short circuit protection. These features work together to provide maximum power and protect against current overload, short circuits, and thermal dissipation.

The AP2311AS-13 also features a slew rate control to prevent noise and spiking. The slew rate is the rate at which the voltage output changes in response to changes in the input voltage. A slower slew rate reduces the rate of change in output voltage, reducing the possibility of electrical noise, while higher slew rates allow for faster response and greater control over voltage output.

The AP2311AS-13 is designed with a low quiescent current in order to help increase system efficiency. The low quiescent current reduces the amount of power consumed when the device is in standby mode, allowing for lower overall power consumption.

Lastly, the device offers fault detection and protection to help protect against over-voltages and short-circuits. The fault detection feature detects when an over-voltage condition exists and shuts off the device. This helps prevent devices from being over-powered, which can damage components.

Conclusion

The AP2311AS-13 is a low-voltage PMIC designed for load drivers, power distribution switches and other applications. The device integrates three independent channels and features a wide input voltage range, low quiescent current, high-side current sensing, fault detection, and a slew rate of 2A/μs. The AP2311AS-13 is suitable for a wide range of applications including driving high-power LEDs, powering processors and other ICs, powering batteries, and in battery-powered applications such as smartphones, tablets and wearables.
