The AUIR3313 is a single-channel power distribution switch and load driver, ideal for portable applications. The power management integrated circuit (PMIC) features an adjustable, turn-on threshold voltage. This enables it to be used in a wide range of power distribution and load driving applications in the highest power density systems. The switch features a high slew rate of 66V/us and a very low quiescent current of 0.25A, both of which are important for power-efficient switching and maximizing usable battery life. It also provides an adjustable current limit of 20mA to maximize system safety. Additionally, the integrated compensation circuitry ensures high accuracy and reliable operation in a wide range of applications.

The AUIR3313 is designed to manage the simultaneous delivery of multiple loads in battery-powered systems while offering high power efficiency and reliability. It is perfect for experienced designers looking for a quick-to-configure solution with low development costs. The device provides one switchable output and two discrete low-side MOSFETs which can operate in a single- or dual-switch operating mode. It is designed primarily for battery applications and is optimized for high performance and small size.

The AUIR3313’s three switchable output stages control the current flow from the input to the load. A power-on reset circuit keeps the output disabled until the supply voltage is applied to the device. Three input pins enable the designer to set the desired threshold voltage for the power-on reset. An enable pin turns the device on and off, effectively isolating the system from the battery and protecting the system from excessive power consumption. The device\'s PWM input pin allows for real-time current control.

The single-channel output employs hysteretic architecture with an adjustable current limit to provide fast rise and fall times of 6nsec and 1.3msec respectively. The output isolates the system from the battery by enabling and disabling the current flow. The two low-side MOSFETs connected to the output can be independently enabled or disabled to maximize or minimize current flow. This helps to optimize overall system efficiency in a wide variety of applications. In addition, the low power consumption of the AUIR3313 helps to maximize battery life.

The AUIR3313 is an easy-to-use power distribution switch and load driver for portable applications, offering maximum efficiency and system protection. It is ideal for modern electronic designs that require fast, powerful, low-power solutions. Its adjustable current limit, adjustable turn-on threshold voltage, and low power consumption make it optimal for a wide variety of applications, both for the novice and experienced designer.
