The MAX1737EEI+ integrated battery charger is a sophisticated power management IC (PMIC) meant to recharge single-cell lithium ion (Li+) batteries. In addition to its battery charging functions, it includes a highly precise voltage monitor, a logic power supply, and an external MOSFET driver, which provide new levels of cost savings and system integration in applications that require battery charging. This article will explore the field of applications and the working principle of the MAX1737EEI+.

The MAX1737EEI+ is a highly integrated PMIC with a wide-ranging range of battery charging applications. It is suitable for many kinds of battery-operated devices, including cell phones, PDAs, portable MP3 players, and digital cameras. It is well suited for use in applications that require a compact, low-cost battery charger, such as a pocket-sized charger for a rechargeable battery. The MAX1737EEI+ is also ideal for use in applications that require its ability to drive an external MOSFET, such as a hot-swap backup battery for a portable system.

The working principle of the MAX1737EEI+ is based on a buck-boost switching regulator architecture. In this scheme, the charger provides a fixed input voltage and current to the battery, while sensing the battery\'s voltage and adjusting its output voltage in order to maintain a fixed battery voltage. When the battery is discharged, the charger begins to charge the battery. When the battery reaches its maximum charge, the charger shuts itself off, preventing overcharging and extending the battery\'s life.

The MAX1737EEI+ is also endowed with several features that allow it to meet specific application requirements. It features a programmable high-voltage and low-voltage cutoff, as well as a programmable current limit and delayed low-voltage cutoff. These features enable the charger to protect the battery from overcharging and prevent undercharging, ensuring an optimal charging rate. In addition, the MAX1737EEI+ includes integrated thermal control, allowing it to maintain battery charging rates even during times of high thermal dissipation. Its integrated logic power supply provides a full-scale output, allowing it to drive high-power loads. Finally, the MAX1737EEI+ includes an external MOSFET driver, enabling it to activate accessories, such as a cooling fan, or provide logic control to an external device.

The MAX1737EEI+ integrated battery charger is a powerful and versatile PMIC battery charger designed with a wide range of applications in mind. Its innovative buck-boost switching regulator architecture enables it to provide optimal charging rates to single-cell Li+ batteries, while its integrated thermal control, external MOSFET driver, and logic power supply ensure system integration and control. With its flexible features and robust design, the MAX1737EEI+ is ideal for use in a variety of applications.
