DESCRIPTION
The L6237 is a Triple Half bridge Driver intended
for use in brushless DC motor applications. The
device is designed to drive a Three Phase,
Brushless DC Motor, Typically used in Rigid Disk
Drives. Power drivers are fabricated in DMOS
Technology and feature Fast Internal Recircula-
tion Diodes. All logic inputs are CMOS/TTL com-
patible,and an internal TransconductanceLoop is
included for linear motor speed control. Upper N-
Channel DMOS Transistors are driven via an In-
ternal Step-Up Converter. The IC will be manu-
factured in a plastic TQFP64 surface
package.
