PM8841

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.

SOT23-5

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.

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

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.

 Input and output UVLO

 Wide operating temperature range:
