DESCRIPTION
The EMB1428 Switch Matrix Gate Driver IC is
designed to work in conjunction with EMB1499
DC/DC Controller IC to support TI’s switch matrix
based active cell balancing scheme in a battery
management system. The EMB1428 provides 12
floating MOSFET gate drivers necessary for
balancing up to 7 battery cells connected in a series
stack. Multiple EMB1428 ICs may be used together
to balance a stack of more than seven battery cells.
The EMB1428 integrated circuit interfaces with the
EMB1499 DC/DC controller to control and enable
charging and discharging modes. The EMB1428 uses
an SPI bus to accept commands from the main
controller (CPU/MCU) on which battery cell should be
charged or discharged and to report back any faults
to the main controller (CPU/MCU).
