PMIC - Power Distribution Switches, Load Drivers

The AP2161MPG-13 is a high performance single-channel Power Distribution Switch, Load Driver and Buck switching regulator, that has flexibility and reliability for a wide range of applications. It contains one load driver, one buck switching regulator, and one balanced voltage triangle (Vtrip) detector for current sense.

The AP2161MPG-13 is used to control the power supply of electronic equipment with a consistent, stable, and reliable supply of power. It can be used for many applications including mobile devices, consumer electronics, industrial equipment, and automotive electronics. The AP2161MPG-13 supports a wide range of voltage and current ratings to accommodate a variety of design requirements. It features a small footprint, low power dissipation, and high efficiency with minimal ripple noise.

The AP2161MPG-13 has several functions including voltage monitoring, current limiting, load disconnect and automatic power-down, over current protection, and reverse battery protection. It is designed to perform a wide range of functions such as powering up and down the device, controlling the voltage and current, protecting the load and battery, monitoring the temperature, and controlling the development cycles.

The load driver controls the load current when operating in the buck mode. It has adjustable over-current protection and can be over-loaded through a differential input to the load driver. The load can be controlled by adjusting the duty cycle using the PWM signal from the microprocessor. The load driver can be used to protect the switch from both high and low voltage transients, as well as from short-circuits and over-loading of the switch.

The buck switching regulator is used to supply the required power to the output load. It has a wide input voltage range and low power dissipation. The buck switching regulator is capable to work with both constant voltage and constant current sources. The buck switching regulator has an integrated current sense protection to limit overcurrent through the load and keep the output voltage within specified limits. The output voltage can be programmed using a 4-bit A/D DAC from the microcontroller.

The balanced voltage triangle (Vtrip) detector is used to sense the output current and control the load. The Vtrip detector senses the output current and adjusts the switching duty cycle or the output voltage depending on the application. It has a low quiescent current, high accuracy, and low power dissipation. The Vtrip detector is designed to be tolerant to overvoltage and undervoltage as well as short-circuit conditions.

The AP2161MPG-13 is a cost-effective and reliable Power Distribution Switch, Load Driver and Buck switching regulator, which is suitable for a variety of applications. It integrates several functions such as voltage monitoring, current limiting, load disconnect, over current protection, and reverse battery protection in a single package, saving space and cost. This device is an ideal solution for mobile, consumer, industrial and automotive electronics that require a robust, versatile and reliable power supply solution.
