PM8841D

PM8841 Low-Side Gate Driver

STMicroelectronics PM8841 Low-Side Gate Driver 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 PM8841 output can sink 1A and source 0.8A. The input levels of the driver are derived by the voltage present at the IN_TH pin (between 2V and 5.5V). This pin is typically connected at the same voltage of the microcontroller supply voltage. The PM8841 device includes both input and output pull-down resistors. UVLO circuitry for input and output stages is present preventing the IC from driving the external MOSFET in unsafe condition.
