SNVSAQ6A – NOVEMBER 2016 – REVISED JUNE 2017 LM5170-Q1 Multiphase Bidirectional Current Controller
1 Features 3 Description The LM5170-Q1 controller provides the essential high
voltage and precision elements of a dual-channel
bidirectional converter for automotive 48-V and 12-V
dual battery systems. It regulates the average current
flowing between the high voltage and low voltage
ports in the direction designated by the DIR input
signal. The current regulation level is programmed
through analog or digital PWM inputs. 1 AEC-Q100 Qualified for Automotive Applications:
