AP2176MPG-13 Application Field and Working Principle

Power Distribution Switches, Load Drivers

The AP2176MPG-13 is a power management IC (PMIC) from Alpha and Omega Semiconductor, Inc. that integrates dual power distribution switches, dual Load Drivers, and a voltage detector into a single package. It is designed to provide digital control and protection of system power supply lines. The device also features an on-chip voltage detector that can monitor voltage, current and temperature.

Application Field

The AP2176MPG-13 is most commonly used in medium-power applications such as laptop and notebook PCs, LED displays, automotive HVAC systems, point-of-sales terminals, industrial sensors and controllers, and working systems and triggers. The device features integrated MOSFETs and drivers that can handle up to 6A of load current, as well as a voltage detector that can monitor voltage, current and temperature.

Working Principle

The AP2176MPG-13 incorporates two independent power distribution switches and two independent low-side Load Drivers. The power distribution switches can be used to switch main power supplies in the system or to switch the voltage supplied to the Load Drivers for power delivery. The integrated low-side Load Drivers can be used to control the current and output voltage levels of external loads. The device also features an on-chip voltage detector that is used to monitor voltage, current, and temperature.

The AP2176MPG-13 operates in two modes: sleep mode and active mode. In sleep mode, the device is inactive, drawing minimal supply current. In active mode, the Load Drivers, power distribution switches and voltage detector are activated, and the outputs can be adjusted via digital inputs. The device also has an integrated power-on reset circuit that is used to ensure proper operation when power is initially supplied to the system.

The AP2176MPG-13 is designed to be an efficient and reliable power management solution for medium power applications. With its integrated power distribution switches and Load Drivers, as well as its on-chip voltage detector and power-on reset circuit, the device offers a cost-effective method for controlling system power supply lines and external loads.
