FEATURES  
DESCRIPTION  
The EMB1499Q bidirectional current dc/dc controller  
IC works in conjunction with the EMB1428 switch  
matrix gate driver IC to support TI’s switch matrix  
based active cell balancing scheme for a battery  
management system. The EMB1499Q provides three  
PWM MOSFET gate signals to a bidirectional forward  
converter so that its output current, either positive or

negative, is regulated around  
a
user-defined  
magnitude. This inductor current is channeled by the  
EMB1428 through the switch matrix to the cell that  
needs to be charged or discharged. In a typical  
scheme, the EMB1499Q-based forward converter  
exchanges energy between a single cell and the  
battery stack to which it belongs, with a maximum  
stack voltage of up to 60 V. The switching frequency  
is fixed at 250 kHz. The EMB1499Q senses cell  
voltage, inductor current and stack current and  
provides protection from abnormal conditions during  
balancing.

EMB1499Q is an Automotive Grade Product  
that is AEC-Q100 Grade 1 Qualified (–40°C to  
+125°C Operating Junction Temperature)  
APPLICATIONS  
The EMB1499Q also provides an active clamp timing  
signal to control an external FET driver for the  
primary-side active clamp FET. The EMB1499Q is  
enabled and disabled by the EMB1428. Fault  
conditions detected by the EMB1499Q are  
communicated to the EMB1428 through the DONE  
and FAULT pins.
