APPLICATION INFORMATION

Reference Design Circuits

Half Bridge Motor Driver

T

In

half-bridge

converter

topology,

the

MOSFETs are driven alternately with some dead

time. Therefore, INH and INL are driven with

alternating signals from the PWM controller. The

input voltage can be up to 100V in this

application.
