EMB1428QSQE/NOPB Description

Short technical summary and product information.

The Texas Instruments EMB1428QSQE/NOPB is an Automotive Grade switch matrix gate driver IC 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 EMB1428QSQE/NOPB units can be used together to balance stacks exceeding seven cells. The device interfaces with the EMB1499 controller to manage charging and discharging modes, utilizing an SPI bus for commands and fault reporting to the main controller (CPU/MCU).

 

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 and is surface-mount compatible.

 

Designed for automotive applications, the EMB1428QSQE/NOPB is AEC-Q100 Grade 1 Qualified. It supports cell balancing, multi-cell configurations, and stackable operation through its built-in interface. The maximum stack operating voltage is 60V.
