EMB1499Q Bidirectional Current DC-DC Controller

Check for Samples: EMB1499Q

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

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.

External Voltage

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.
