Server battery backup units (BBU)
Infineon offers a wide range of products for battery back-up units in applications like telecom and datacenters, both for the BMS and the DC-DC stage
A BMS ensures high performance and safe operation of Li-ion batteries. It is a must-have, and performs actions such as SOC (state of charge) and SOH (state of health) estimations. In battery back-up systems in applications like telecom and datacenters, a BMS circuit is coupled with a DC-DC converter to ensure a regulated output voltage. The DC-DC stage is bidirectional and usually a buck-boost topology, as either single or multiphase.
Benefits:
- More efficient charge and discharge
- Efficient DC-DC tolopogies
- Accurate battery protection
- Safe and reliable solution
Infineon integrated circuits and designs help you to lay out your battery management system. Careful design considerations on charging and discharging processes on battery protection and cell monitoring will support you throughout your design. In fact, our design support solutions can help you to overcome design challenges and support your success in developing more efficient, longer lasting, and more reliable battery-powered applications. Our tools are created by engineers for engineers, and will support you in every phase of your design, from comparing the different products to simulations, and of course ready-to-use reference designs.
The evolution of switched-mode power supply (SMPS) topologies enables designers to ensure safe charging and discharging of the equipment’s battery using bidirectional converters through the same terminal. However, to meet the safety requirements and prevent damage and failures, those SMPS need to be equipped with a protection switch. Βidirectional switches are widely used in Battery Management Systems (BMS) to charge/discharge and protect against various failures like inrush current, overcurrent, short-circuit, reverse voltage, or overvoltage and undervoltage.
Thanks to our more than 40 years of MOSFET experience and continuous package and technology innovation, Infineon offers decreased RDS(on) values when moving from OptiMOS™ 3 to OptiMOS™ 5 in the same package to enable better performance in applications such as BDPS where low RDS(on) is critical.

In battery management systems, a compact and reliable solution that powers the entire system is required. Here, several components can be integrated, in order to manage extreme battery voltage fluctuations. Infineon's portfolio of power management ICs (PMICs) meet these requirements and more, including the latest network interfaces and automotive security. PMICs support comprehensive power supplies with a small form factor footprint for system solutions using Infineon's TRAVEO™, AURIX™, and PSoC™ MCU families. Boost function integrated into the PMICs avoids system blackout under extreme battery voltage fluctuations. The low quiescent current of the PMICs reduces the standby current of always-on functions. The PMICs comply with AEC-Q100, and extensive system safety functions help to comply with modern vehicle ECU requirements.
