LM5170PHPR, Switching Controllers Multiphase bidirectional current controller 48-HTQFP -40 to 125
Power\Power Management ICs\Switching ControllersLM5170 Multiphase Current Controller Texas Instruments LM5170 Multiphase Current Controller provides the essential high voltage and precision elements of a dual-channel bidirectional converter. 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. Dual-channel differential current sense amplifiers and dedicated channel current monitors achieve typical current accuracy of 1%. Robust 5A half-bridge gate drivers are capable of driving parallel MOSFET switches delivering 500W or more per channel. The diode emulation mode of the synchronous rectifiers prevents negative currents but also enables discontinuous mode operation for improved efficiency with light loads. Versatile protection features include cycle-by-cycle current limiting, overvoltage protection at both HV and LV ports, MOSFET failure detection, and over-temperature protection.
