LB11600JV
Monolithic Digital IC
Brushless Motor Predriver IC for
Automotive Applications
Overview
The LB11600JV is a direct PWM drive predriver IC appropriate for 3-phase power brushless motors in automotive
applications. This IC can implement either high side PWM drive or low side PWM drive motor driver circuits depending
on the configuration of the output circuits, which use discrete transistors such as MOSFETs or bipolar transistors. In
addition to a full complement of protection functions, including overcurrent, thermal, motor constraint, and undervoltage
protection, the LB11600JV also provides an integrated speed control function. Thus the LB11600JV can implement high
reliability/high functionality drive circuits.
