The PM8851 device is a high frequency single channel low-side MOSFET driver specifically designed to work with digital power conversion microcontrollers, such as the STMicroelectronics STLUX™ family of products.
The PM8851 has complementary output pins to differentiate sink and source driving with a current capability of respectively 1 A and 0.8 A.
The input levels of the driver are derived by the voltage present at the IN_TH pin (between 2 V and 5.5 V). This pin is typically connected at the same voltage of the microcontroller supply voltage.
The PM8851 includes both input and output pull-down resistors.
UVLO circuitry for input and output stages is present preventing the IC from driving external MOSFET in unsafe condition.主な特徴
