STMicroelectronics PM8851D
The PM8851 device 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 PM8851 has complementary output pins to differentiate sink and source driving with a current capability of respectively 1 A and 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).FEATURES

DESCRIPTION
This pin is typically connected at the same voltage of the microcontroller supply voltage. The PM8851 includes both input and output pulldown resistors. UVLO circuitry for input and output stages is present preventing the IC from driving external MOSFET in unsafe condition. Table 1.
