The LM3658SDX is part of the family of battery chargers developed by Texas Instruments. This type of battery charger offers a high level of performance and increased versatility compared to traditional types of battery chargers. It comes with the capability to provide up to 20A of charging current and can charge two batteries simultaneously. The user can also customize the charging parameters to suit individual needs and preferences.

The LM3658SDX battery charger is applicable to a variety of applications, ranging from consumer electronics such as smartphones and cameras to industrial equipment batteries. It also supports various battery chemistries including Li-ion, Li-polymer, NiMH, and lead-acid. It has a high accuracy voltage regulation that helps to reduce overcharging in order to extend battery life.

The lm3658SDX features a very high efficiency buck controller that helps to minimize power losses. This power conversion unit provides a high level of power efficiency and is capable of operating in a wide range of temperatures and harsh environment. The buck controller is also IP67 rated which enables the user to use in outdoor applications. Additionally, it supports multiple input voltage sources and provides protection against overvoltage.

The lm3658SDX also has a powerful system monitor unit. This unit offers a high level of protection that ensures a safe and efficient charging process. It monitors various charging parameters such as current, voltage and temperature to protect the battery from failure or damage. It also supports various communication protocols such as I2C, SMBus, and PMBus for efficient data transfer.

In addition, the lm3658SDX has a programmable watchdog timer that helps to prevent system shutdown in event of rogue conditions. This feature allows the user to adjust the timer settings to enable system self-recovery. The precharge feature helps the battery to reach a fully charged state by turning off the charger after a set time. This helps to save energy and reduce the risk of overcharging the battery.

The working principle of the lm3658SDX is simple. It first receives an input voltage from an external power source and then it uses a buck converter to step down the voltage to the required charging voltage. After that, the voltage is regulated using the system monitor unit and finally, it is sent to the batteries for charging. The system monitor unit constantly monitors the charging parameters in order to ensure a safe and reliable charging process.

The lm3658SDX is ideal for a wide range of battery charging applications due to its wide range of features, such as high efficiency, high accuracy voltage regulation and safety protection. Additionally, it supports various input voltage sources and multiple communication protocols for efficient data transfer. With its high efficiency buck controller and programmable watchdog timer, it ensures a safe and reliable charging process.
