LF21814N

High-Side / Low-Side Gate Driver

Features

Description

 Floating high-side driver in bootstrap operation to

The LF21814N is a high voltage, high speed gate driver

capable of driving N-channel MOSFETs and IGBTs in a

half bridge conﬁguration. The high voltage technology

enables the LF21814N’s high side to switch to 600V in a

bootstrap operation.

600V

 Drives two N-channel MOSFETs or IGBTs in a half

bridge conﬁguration

 1.9A source / 2.3A sink output current capability

 Outputs tolerant to negative transients

 Wide low side gate driver supply voltage: 10V to 20V

 Logic input (HIN and LIN) 3.3V capability

 Schmitt triggered logic inputs with internal pull

The LF21814N logic inputs are compatible with

standard TTL and CMOS levels (down to 3.3V) to

interface easily with controlling devices. The driver

outputs feature high pulse current buﬀers designed

for minimum driver cross conduction.

down

 Under Voltage Lockout (UVLO) for high and low side

The LF21814N is offered in SOIC(N)-14 package

and operate over the extended temperature range of

-40 °C to +125 °C .

drivers

 Extended temperature range: -40°C to +125°C

 Motor Controls

 DC-DC Converters

 Class D Power Ampliﬁers

Typical Application

SOIC(N)-14

Up to 600V
