The Texas Instruments EMB1428QSQX/NOPB is an Automotive Grade switch matrix gate driver designed for active cell balancing within battery management systems. It works in conjunction with the EMB1499 DC/DC Controller IC to facilitate TI's switch matrix-based active cell balancing scheme.
This IC provides 12 floating MOSFET gate drivers, enabling the balancing of up to 7 battery cells connected in a series stack. Multiple EMB1428QSQX/NOPB devices can be used together to balance larger battery stacks. The device interfaces with a main controller via an SPI bus, accepting commands for charging or discharging specific battery cells and reporting any faults.
Key electrical specifications include a maximum input voltage of 5.5V and a typical operating current of 750µA. The operating temperature range is -40°C to 125°C (TJ). The device is housed in a 48-WQFN (7x7 mm) package, suitable for surface mounting.
Designed for applications requiring precise battery cell management, the EMB1428QSQX/NOPB supports multi-cell configurations and is stackable for scalability. Its features are crucial for optimizing battery performance and longevity in various power management systems.
