PM8841 1 A low-side gate driver Datasheet - production data Description 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. SOT23-5 The PM8841 output can sink 1 A and source 0.8 A. The input levels of the driver are derived by the Features voltage present at the IN TH pin (between 2 V and 5.5 V). This pin is typically connected at the Low-side MOSFET driver same voltage of the microcontroller supply 1 A sink and 0.8 A source capability voltage. External reference for input threshold The PM8841 device includes both input and Wide supply voltage range (10 V 18 V) output pull-down resistors. Input and output pull-down resistors UVLO circuitry for input and output stages is Short propagation delays present preventing the IC from driving the external MOSFET in unsafe condition. Input and output UVLO Wide operating temperature range: -40 C to Table 1.
