PM8841:Single channel low-side gate driver

The PM8841 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 1 A and source 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 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.
