DS2434-E Application Field and Working Principle

As part of the DS2434-E class of Programmable Battery Management ICs (PMICs) from the industry leading manufacturer Dallas Semiconductor, the DS2434-E offers a unique configuration and wide range of capabilities. Designed to replace a number of stand alone battery management systems, the DS2434-E replaces multiple components, contact points and control functions with a single cost effective solution. Ideal for complex battery systems in handheld devices, automotive applications, consumer electronics and medical equipment, the DS2434-E provides enhanced reliability, cost savings and improved performance.

The primary feature of the DS2434-E is its range of voltage measurements that can be configured and optimized to suit a given application. The device supports multiple voltage range selections and the user interface is user friendly and allows for the adjustment of parameters quickly and easily. The DS2434-E also features a programmable level monitoring circuit, which monitors the voltage of the main battery and produces an SP-L alarm signal if the voltage drops below a predetermined threshold.

An additional feature of the DS2434-E is its ability to monitor temperature and evaluate the battery capacity. The integrated System Calibration enables an optimal adaptation to any type of battery under the given temperature conditions. This helps the DS2434-E to optimize the system performance while ensuring a safe and reliable operation.

The DS2434-E incorporates a state-of-the-art system protection architecture enabling it to protect the battery and the load in case of overload or short circuit conditions. In addition, the user can configure the device to control the system’s performance by programming the feedback gain, voltage limitation and voltage protection. This ensures an optimal operation of the devices, a safe connection and the prevention of any potential damage.

The device’s SMBus interface allows for a full control of the device by software. The SMBus can be used to set up the operating parameters, monitor the battery status, trigger alarms and power up the system. The flexibility of the SMBus interface makes it a suitable device for any application where distributed control is required. This can include multi-cell battery systems and distributed sensor networks.

Finally, the DS2434-E features a wide supply range from 2.7V to 5.5V, making it suitable for all types of battery system, including single-cell, multi-cell and linear cell systems. The low power dissipation, wide voltage range, low-noise operation and low-voltage protection make the device a perfect choice for any high-performance battery system.

Conclusion

The DS2434-E is a powerful, cost effective and efficient battery management IC from Dallas Semiconductor. It offers a wide range of voltage measurements and system protection features and its compact design enables it to be easily integrated into battery systems. Its user-friendly configuration and SMBus interface helps make it a suitable device for a wide range of applications.
