Overview
PM8851 1 A low-side gate driver with configurable asymmetric sink/source SOT23-6L Features  Low-side MOSFET driver  1 A sink and 0.
8 A source capability  Complementary outputs for source and sink driving  Ext.
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  SOT23-6L package Applications  SMPS  Digital lighting  Wireless battery chargers  Digitally controlled MOSFETs Datasheet - production data Description 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).
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.
