TI Launches Multi-Phase Bidirectional Current Controller
Published2017.03.21 11:26TI has introduced the industry's first fully integrated multi-phase bidirectional DC/DC current controller (LM5170-Q1) that efficiently transfers more than 500W per phase between 48V and 12V automotive battery systems.
The highly integrated analog controller LM5170-Q1 employs an innovative average current mode control technique to overcome the limitations of fully digital control approaches that require numerous components.
TI will participate in the upcoming APEC (Applied Power Electronics Conference) and showcase the LM5170-Q1 controller.
In hybrid electric vehicles that use a high-voltage 48V battery and a standard 12V automotive battery, design engineers typically use digital control methods to manage the dual battery system, which includes multiple discrete components such as current sense amplifiers, gate drivers, and protection circuits.
To address these issues while improving performance and system reliability, TI provides a mixed-signal architecture. In this mixed-signal architecture, the microcontroller performs high-level intelligent management, while the highly integrated analog controller LM5170-Q1 provides power conversion.
