  • 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.

    Key Features

    • Low-side MOSFET driver
    • 1 A sink and 0.8 A source capability
    • External reference for input threshold
    • Wide supply voltage range (10 V ÷ 18 V)
    • Input and output pull-down resistors
    • Short propagation delays
    • Input and output UVLO
    • Wide operating temperature range: -40 °C to 125 °C
    • SOT23-5 package
