The LM5171 controller provides the high voltage and precision elements of a dual-channel bidirectional converter. Examples include dual battery systems. The LM5171 supports multiphase parallel operation with balanced current sharing in each phase. The LM5171 also supports independent channel bi-directional operations making it versatile as standalone controller operating as multiphase Buck/Boost or independent Buck or Boost.

The dual-channel differential current sense amplifiers and dedicated channel current monitors achieve typical accuracy of 1%. The robust 5A half-bridge gate drivers are capable of driving parallel MOSFETs for scaling more power per channel. The controller can be dynamically programmed to operate in either the diode emulation mode (DEM) or forced PWM (FPWM) mode. Versatile protection features include cycle-by-cycle current limiting, overvoltage protection at both HV and LV ports, and overtemperature protection and urgent shutdown latch.
