LV5685PV数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

The LV5685PV is a multiple output linear regulator IC, which allows reduction of quiescent current. The LV5685PV is specifically designed to address automotive infotainment systems power supply requirements. The LV5685PV integrates 5 linear regulator outputs, 2 high side power switches, I2C-bus communication, ACC detection, battery voltage detection, over-current limiter, overvoltage protection and thermal shut down. Supply for VDD and SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared to the existing model.
