PM8851

1 A low-side gate driver with configurable asymmetric sink/source

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.

SOT23-6L

The PM8851 has complementary output pins to

differentiate sink and source driving with a current

capability of respectively 1 A and 0.8 A.

Features

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.

 Low-side MOSFET driver

 1 A sink and 0.8 A source capability

 Complementary outputs for source and sink

driving

The PM8851 includes both input and output pull-

down resistors.

 Ext. reference for input threshold

 Wide supply voltage range (10 V ÷ 18 V)

 Input and output pull-down resistors

 Short propagation delays

UVLO circuitry for input and output stages is

present preventing the IC from driving external

MOSFET in unsafe condition.

 Input and output UVLO
