Multi-phase bidirectional current controller 'LM5170-Q1'
The LM5170-Q1 controller achieves high voltage and high precision essential for dual-channel bidirectional converters in automotive 48V and 12V dual battery systems. It regulates the average current flowing between the high voltage and low voltage ports in the direction specified by the DIR input signal. The current regulation level is programmed via analog or digital PWM input. With dual-channel differential current sensing amplifiers and dedicated channel current monitors, a current accuracy of 1% at standard values is achieved. A robust 5A half-bridge gate driver drives parallel MOSFET switches, providing over 500W of power per channel. 【Features】 ■ AEC-Q100 certified for automotive applications ■ Maximum ratings of 100V HV port and 65V LV port ■ 1% accuracy bidirectional current regulation ■ 1% accuracy channel current monitoring ■ 5A peak half-bridge gate driver *For more details, please contact us.
