The EMB1499QMHE/NOPB from Texas Instruments is an Automotive Grade Bidirectional Current DC-DC Controller IC. It is designed to work with the EMB1428 switch matrix gate driver for active cell balancing in battery management systems. This controller provides three PWM MOSFET gate signals to a bidirectional forward converter, regulating output current for charging or discharging individual cells within a battery stack.
Key electrical specifications include a maximum stack operating voltage of 60V, an input voltage range of 10V to 56V, and a fixed switching frequency of 250 kHz. It supports 6 to 14 series cells and communicates via SPI. The device operates efficiently with a typical operating current of 1000 µA.
Designed for robust performance, the EMB1499QMHE/NOPB features comprehensive fault detection, including UVLO, current limit, OVP/UVP sense, thermal shutdown, and a watchdog timer. It is housed in a 28-HTSSOP package suitable for surface mounting.
This IC is AEC-Q100 Grade 1 Qualified, operating reliably within an ambient temperature range of -40°C to 125°C, making it suitable for demanding automotive applications.
