AP2401ASN-7 is a power distribution switch and load driver. It is a low cost and highly integrated single chip solution for power management, motor power control and system distributed power management applications. It is designed to provide a low-on-resistance, low-drop-out power control solution for portable battery applications with minimal component count and reduced board space. It also offers a low standby current which helps conserve battery power while maintaining system performance.

The AP2401ASN-7 is fully integrated with N-channel MOSFETs that provide ultra-low-on-resistance power switching. It also includes a load driver to support high current loads. The device takes its power from the system battery and provides a power-on reset for the system. The device can be used in a variety of applications such as: smartphones, tablets, portable music players, wearables and other battery powered devices.

The AP2401ASN-7 employs an input voltage range of 0.5 Volts to 3 Volts, and a quiescent current of 4uA, making it ideal for use in low-power applications. It also has built-in thermal protection, over-voltage protection, over-current protection and over-temperature protection. The device is also designed to support hot-plugging of power connectors without the risk of damaging the device or system.

The device provides a single-ended, open-drain power switch and a two-level open-drain load driver for a wide range of load types. The load driver controls a load by providing a fast high-side switch and a slow low-side switch. This feature allows for the implementation of a wide range of power application circuits with minimal additional components.

An on-chip low-pass filter is provided for filtering of the output voltage, and a load control register is included for setting the load current limit. The device also includes an on-chip SPI interface for monitoring and tuning of the output voltage and current levels.

The AP2401ASN-7 is a highly integrated single-chip solution for portable device power management that is designed to reduce board space and component count while preserving energy. It can be used in a variety of applications where low-drop-out, low-on-resistance power control is needed, such as smartphones, tablets, portable music players, and wearables.
