3 Description

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-bycycle

current limiting, overvoltage protection at both

HV and LV ports, and overtemperature protection and

urgent shutdown latch.
