Renesas Unveils New Multi-Cell Battery Front End Family for High-Cell Count, High-Voltage Systems

New RAA48920x ICS Speed Battery Development for Mobility, UPS, and Energy Storage Systems With Lower Development Costs and Flexible Cell Balancing

Renesas Electronics Corporation (TSE:6723), a leading provider of advanced semiconductor solutions, announced today a new family of multi-cell full battery front end (BFE) ICs for battery management systems (BMS) designed for larger, high-voltage battery packs that power e-scooters, energy storage  , high-voltage power tools, and other high-voltage equipment. The new ICs provide quick, flexible cell balancing up to 200 mA+, which is crucial for fast recharging and high utilization in large battery packs with a hot plug tolerance of up to 62V.

"BMS serves as the battery pack's "brains," and the growing use of  BMS  in UPS and data centers is driving up demand for high-performance ICs that can support higher voltage and larger cell battery pack sizes," said Andrew Cowell, Vice President, Mobility, Infrastructure, and IoT Power Business Division at Renesas. "We've built our new RAA489206 and RAA489204 ICs with the performance, flexibility, and integration that make it easier than ever for customers to simplify the design process and create robust, cost-effective battery systems for the growing mobility,  UPS backup, and energy storage markets," says the company.

The RAA489206 provides full high-side battery protection and monitoring for 4S to 16S cell  battery  packs and is designed for higher voltage mobility applications where bigger cell counts and temperature variance across cells are more likely to cause cell-to-cell imbalances. When compared to previous-generation devices, the RAA489204 offers improved daisy chain operation, faster device-to-device communication, and improved diagnostics, as well as internal cell balancing options and support for higher voltages and cell, counts required by UPS systems, grid backup, and other energy storage systems.

The high integration of the new ICs streamlines the design cycle and lowers the system BOM costs for clients, cutting design and BOM selection time from months to weeks. The ICs also have a lot of built-in self-diagnostics, which improves safety, reduces firmware workload, and makes it easier to meet safety regulations. Pin-to-pin compatibility with prior Renesas BFE devices greatly streamlines the design cycle, allowing customers to migrate to the new BFE ICs quickly and seamlessly.

Key Features of the RAA489206

• 16 cell voltage measurements

• Internal (10 mA) and external (200 mA) cell balancing options

• Operating voltage range of between 12V and 55V with +/- 10mV voltage measurement accuracy

• Up to 20 cm2 board space reduction

• Low-side current sense measurement

• High-side charge/discharge FET battery protection

Key Features of the RAA489204

• Operating voltage range of between 10V and 65V with +/- 10mV voltage measurement accuracy and +/-190mV pack voltage measurement accuracy

• Measures and performs read-back on all voltages, temperatures, and diagnostics for 112 cells in less than 10ms

• Cell balancing with both internal and external FETs supported

• Up to 6 external thermistor inputs

• Robust, low-power (typically 1mA when transmitting 10% of the time) daisy chain communications

• Stackable up to 30 ICS

The RAA489206 and RAA489204 ICs are ideal for BMS applications that require a lot of power. Renesas has created comprehensive solutions for a number of applications by combining complementary power, analog, and microcontroller components. A new 20-28 cell Battery Management System (up to 118V) is included, completing the BMS system.
