PMIC - Battery Chargers
MAX8731ETI+ Application Field and Working Principle
The MAX8731ETI+ is a low-cost power management integrated circuit (PMIC) typically used as battery chargers for portable electronic devices. It comes in a small 5-pin package and is typically used with lithium-ion and other similar rechargeable batteries.
The MAX8731ETI+ provides an easy-to-use, low-cost solution for on-board battery charging. It features fast charging via an integrated switched-mode charger that can be used with a wide range of batteries, including 3.6V, 7.2V and 14.4V li-ion batteries. It is also capable of performing features such as temperature and current sensing, over-temperature protection, and short-circuit protection.
In terms of functionality, the MAX8731ETI+ PMIC contains several key elements. First, its charge current setting, which has a range from 50mA to 2A, can be adjusted using an external resistor. The charger current is adjustable via the protection circuit block that includes a programmable current limit, over-temperature protection, and a battery-discharge control switch. Furthermore, the integrated over-voltage protection circuit ensures that the charger does not exceed the battery voltage rating.
The MAX8731ETI+ also includes an integrated switching converter with a temperature-compensated feedback loop to ensure a stable charging voltage. The MAX8731ETI+ also features a compact 5-pin package and is thermally optimized to minimize power dissipation. This makes the PMIC suitable for high-density applications.
The MAX8731ETI+ is a high-performance, low-risk solution for battery-based systems. Its programmable charge current setting makes it suitable for applications over a wide range of battery capacities, and its integrated protection circuits ensure maximum safety. Its low-cost nature also makes it suitable for portable battery applications, such as smartphones, tablets, and other wearables. Ultimately, the MAX8731ETI+ offers customers a simple and cost-effective solution for charge management.
