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.
Dual-channel differential current sense amplifiers and dedicated channel current monitors achieve typical current accuracy of 1%. Robust 5-A half-bridge gate drivers are capable of driving parallel MOSFET switches delivering 500 W 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 overtemperature protection.
