PM8841D

PM8841D is a high frequency single channel low-side MOSFET driver in a 5 pin SOT23 package. It is specifically designed to work with digital power conversion microcontrollers, such as the STMicroelectronics STLUX™ family of products. The PM8841 output can sink 1A and source 0.8A. The input levels of the driver are derived by the voltage present at the IN_TH pin (between 2V and 5.5V). 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. Typical applications include SMPS, digital lighting, wireless battery chargers and digitally controlled MOSFETs.

• External reference for input threshold
• Wide supply voltage range (10V ÷ 18V)
• Input and output pull-down resistors
• Short propagation delays
• Input and output UVLO
• Wide operating temperature range from -40°C to 125°C
