Overview
PM8841 SOT23-5 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 Applications  SMPS  Digital lighting  Wireless battery chargers  Digitally controlled MOSFETs 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.
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.
