Datasheet - production data
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
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
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.
