LF21844N

Half-Bridge Gate Driver

Description

Features

LF21844N 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

LF21844N’s high side to switch to 600V in a bootstrap

operation.

 Floating high-side driver in bootstrap operation to

600V

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

bridge conﬁguration

 1.4A source / 1.7A sink output current capability

 Outputs tolerant to negative transients

 Programmable dead time to protect MOSFETs

The LF21844N 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. Programmable dead time, by an external

resistor, provides more system level ﬂexibility.

 Wide low-side gate driver supply voltage:

10V to 20V

 Wide logic supply voltage oﬀset voltage: -5V to 5V

 Logic input (IN and SD*) 3.3V capability

 Schmitt triggered logic inputs with internal

The LF21844N is oﬀered in SOIC(N)-14 package. It operates

over the extended temperature range of -40 °C to +125 °C .

pull up and pull down

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

low side drivers

 Extended temperature range:-40^oC to +125^oC

Applications

 DC-DC Converters

 AC-DC Inverters

 Motor Controls

 Class D Power Ampliﬁers

Typical Application

SOIC(N)-14

Up to 600V
