The LTC4041 compatible with both 5V and 3.6V Li-Ion/Polymer Battery provides a high level of safety, performance and system cost over a wide range of battery voltages. This feature allows designers to select from a large range of off-the-shelf or custom battery cells. The device is suitable for a variety of applications where a non-disruptive battery balancing system is required such as consumer and industrial electronics, communications, portable, and medical applications.

When a full charge is achieved, the LTC4041 wears the power-limited mode and halts the charge in order to prevent any damage caused by over-charging. However, the device provides the option to increase the charge voltage as needed in order to reduce the battery charge time. The LTC4041 features an internal timer and current monitor for charging. When the maximum charging time (typically 7 hours) is reached, the device stops the charging process.

The LTC4041 regulates the voltage and current of the Li-ion battery cells, while maintaining its voltage within a safe operating window. During normal operation, the device measures the input voltage and the current to calculate the total battery charge. The LTC4041 then utilizes an algorithm to monitor and balance the cells which ensures that each cell is within the same voltage range. This process further extends the life of the Li-Ion/Polymer battery.

In order to increase the safety of the Li-Ion/Polymer cell, the LTC4041 has two built-in safety features. The first is the overtemperature protection which shuts down the device when the charging current reaches too high of a temperature. The second safety feature is the reverse current protection which blocks any reverse current from entering the battery. This feature prevents damage to the battery cell due to unintentional external charging.

In addition, the LTC4041EUFD#PBF includes a low power shutdown feature to reduce system power consumption. This feature allows the device to enter a low power state when the battery is not being charged. This feature reduces system power consumption by up to 50%. The device also features an adjustable mischarging voltage, which allows the designer to increase the charging voltage to reduce the battery charge time.

In addition, the LTC4041EUFD#PBF includes protection against over-voltage and under-voltage to prevent over-charging or deep discharging of the battery. This feature is especially beneficial for applications where the battery is expected to be exposed to extreme voltage conditions.

The LTC4041EUFD#PBF is a high-efficiency charger designed to provide a safe and reliable power management and charging system for Li-Ion/Polymer cells. With advanced protection and features such as a low power shutdown, current monitor, and adjustable mischarging voltage, the LTC4041EUFD#PBF provides maximum flexibility and reliability. It is also suitable for a wide range of consumer and industrial applications, making it an ideal solution for any energy storage related application.
