The MCP73834T-CNI/UN is a highly integrated Low-Voltage Power Management Unit (PMU) from Microchip. This device is specifically designed for two important power management applications: battery charging and high-efficiency PMU solutions.

The MCP73834T-CNI/UN\'s battery charging feature enables applications with rechargeable batteries to detect the presence of a battery, maintain it at the proper level, and store it safely when not in use. The MCP73834T-CNI/UN also includes a variety of PMU solutions that can be used to efficiently manage power in portable, energy-sensitive applications.

The MCP73834T-CNI/UN is particularly suited for designers in the industrial and consumer markets requiring a low-voltage PMu solution. Some of the applications include a variety of portable medical devices, wearables, wireless communications nodes, smart home devices, and embedded systems.

The MCP73834T-CNI/UN features a Charge Pump Regulator (CPR™). It provides up to 1.2A of charging current with low standby current to maximize battery life and maximum charging speed. The device also features an intelligent charge control algorithm that monitors the temperature, voltage and current of the battery being charged to ensure the longest life and safest charging experience. In addition, the MCP73834T-CNI/UN’s low voltage startup makes it compliant with any battery chemistry.

The MCP73834T-CNI/UN also supports a variety of PMU solutions. It includes a programmable power supply, battery backup, current and voltage monitoring, switch control, and sleep power management. Additionally, the MCP73834T-CNI/UN provides programmable voltage scaling to extend system runtime in battery-powered applications.

The MCP73834T-CNI/UN’s advanced power management and control features enable designers to minimize power consumption while maximizing system performance while still managing the most demanding battery charging requirements. Additionally, the device’s configurability options reduce board space and design time making it an ideal choice for designers.

The MCP73834T-CNI/UN’s charge control features can also be used for reverse current protection and battery protection. The reverse current protection prevents battery drain during trickle charge applications, while the battery protection circuitry protects against overcharging and other damaging conditions. The device’s integrated features will also automatically detect battery status and initiate charging when appropriate.

The MCP73834T-CNI/UN is available in a compact MSOP-10 package and is fully specified over the -40°C to +85°C temperature range. Together, these features make the MCP73834T-CNI/UN the perfect solution for designers needing a reliable, feature-rich, low voltage, PMIC - Battery Chargers.
