The MAX77651AEWV+ is a type of battery charger commonly used in power management integrated circuit (PMIC) applications. As a PMIC device, the MAX77651AEWV+ is responsible for providing power supply protection, managing power delivery, and controlling battery charging. The device is a single-cell, standalone Lithium-Ion (Li-Ion) or Li-Polymer (Li-Po) linear battery charger IC specifically designed for charging a wide range of single-cell Li-Ion and Li-Polymer batteries. It features an integrated 20V smart PowerFET power switch, enabling output charging voltages up to 20V, while limiting the charge to 0.6A maximum. The device also features a unique low-power Sleep Mode, which allows the PMIC to be in a low-power state while the battery is not being charged.
In terms of its internal architecture, the MAX77651AEWV+ contains an integrated power FET, power-on reset, voltage reference, temperature sensor, battery charger controller, and switching regulator. The power FET is used to control the linear charging current, based on the programmed current limit. The power-on reset circuit is used to ensure that the battery charge parameters are initialized when the power is disconnected from the battery. The voltage reference circuit is used to provide an internal reference voltage that is necessary for the voltage sensing and charge current control portions of the controller. The temperature sensor is used to monitor the system temperature in order to prevent overheating. The battery charging controller is responsible for controlling the charge current and determining the current state of the battery during the charging process. Finally, the MAX77651AEWV+ includes a switching regulator, which is used to provide a regulated output voltage when the battery is being charged.
The MAX77651AEWV+ is suitable for a wide range of applications, such as portable and wearable devices, digital still cameras, gaming consoles, tablet PCs and other devices that require portable power. It is also ideal for charging single cell Li-Ion and Li-Po batteries, in combination with a battery charging terminal, such as TraceParts Easy Battery. Thanks to its low quiescent current of only 2.0mA and ultra-low power Sleep Mode of 110nA, the device provides an optimal balance between battery lifetime and system performance for low-power applications.
In brief, the MAX77651AEWV+ is a PMIC battery charger, designed for charging a wide range of single-cell Li-Ion and Li-Polymer batteries. It features an integrated 20V smart PowerFET power switch, enabling output charging voltages up to 20V, while limiting the charge to 0.6A maximum. Furthermore, the device includes a low-power Sleep Mode, which allows the PMIC to be in a low-power state while the battery is not being charged. The MAX77651AEWV+ is suitable for a wide range of applications, such as portable and wearable devices, digital still cameras, gaming consoles, tablet PCs and other devices.
