Automotive, 80V dual-channel bidirectional buck/boost controller | PHP | 48 | -40 to 150

The LM5171-Q1

controller provides the high voltage and precision

elements of a dual-channel bidirectional

converter, examples include dual battery systems.

The LM5171-Q1

supports multiphase parallel operation with

balanced current sharing in each phase. The LM5171-Q1 also supports

independent channel bi-directional operation

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 a

typical accuracy of 1%. The robust 5A half-bridge gate

drivers are capable of driving parallel MOSFETs for more

power per channel. Program the controller dynamically to

operate in either diode emulation mode (DEM) or forced PWM

(FPWM) mode. Versatile protection features include

cycle-by-cycle current limiting, overvoltage protection,

overtemperature protection and urgent shutdown latch.
