EG4427 is a cost-effective dual channel independent drive dedicated chip with SD function, which integrates logic signal input processing circuit, level shift circuit, and output drive circuit. It is used for drive circuits in motor controllers, power supplies, and transformers. The power supply voltage range is wide from 3V to 20V, with a static power consumption of less than 1uA. The input channels INA and INB each have a built-in 100K pull-down resistor, and the SD has a built-in 100K pull-down resistor. When the SD input is suspended, it does not affect the output of OUTA and OUTB. The output current capacity is 10+/-1.5/1.5A, and it is sealed with SOP8.
