AP2401A12KTR-E1

The AP2401A12KTR-E1 is a Power Management IC (PMIC) intended for Power Distribution Switches, Load Drivers applications. By combining various subsystems including high and low side MOSFET drivers, linear regulators, and analog signal controllers, the AP2401A12KTR-E1 offers multiple functionalities to regulate and control power supply circuits. It offers a complete power control solution for space-constrained applications with minimal external components.

The AP2401A12KTR-E1 is ideal to reduce power losses when operating at low load currents, and the configurability of the power distribution switches allows to supply the different rails independently. The low-side FETs can be either paralleled, or series connected, giving additional flexibility to the design. This solution can be used in a wide range of portable applications such as mobile phones, tablets, personal media players, digital cameras, and more.

The AP2401A12KTR-E1 works on a configurable and adaptive power distribution stage based on current, voltage and temperature measurements. This allows for system optimization and better performance at low power supplies. Furthermore, the overload/short circuit protection ensures system reliability and improves surge protection levels. All these features make this PMIC an ideal choice for applications where power performances and reliability are essential.

The AP2401A12KTR-E1 provides a constant current output, adjustable over a wide range from 500mA to 1000mA. It switches through two safe ranges, exponentially reducing the power consumption from 500mA to 100mA and from 100mA to 5mA at their respective outputs, with a switching frequency programmable up to 25kHz. The AP2401A12KTR-E1 also provides an input/output protection, which allows for the connection of two secondary power sources in a controlled manner for redundancy or to achieve higher power output.

This PMIC has an internal current limit circuit which limits the delivered current to the output in order to prevent system overheating and overcurrent damage. Furthermore, it features digital soft-start circuitry, which increases the output current gradually at start-up. This prevents OS stability problems caused by in-rush current. Its built-in over-temperature protection and over-current protection circuits ensure the reliability of the system and protect the AP2401A12KTR-E1 from burnout during overload conditions.

To further improve system safety, this PMIC features integrated voltage data detect and verification functions. This helps to protect the system against any potential power supply problems, such as surges in the incoming supply. Additionally, the AP2401A12KTR-E1 offers programmable slew-rate control for optimal power conversion and power stability.

In summary, the AP2401A12KTR-E1 provides a convenient and efficient solution for power distribution, load driving and system protection. Its combination of advanced features, reliable protection and programmable slew rate control ensures system stability, reliability and robust operation. As a result, this PMIC is an excellent solution for space-constrained applications ranging from cameras, tablets, and mobile phones to other applications that require protection, power efficiency and reliability.
