Thermal and Current Limiting Protects Against
Locked Rotor Conditions
Decode Logic with Illegal Code Rejection
HIP4011
Three Phase Brushless DC Motor Controller
Description
The HIP4011 motor driver is intended for three phase Brush-
less motor control at continuous output currents up to 3A. It
accepts inputs from buffered Hall effect sensors and drives
control input. Output “freewheeling” diodes are built in and
output dv/dt is limited to decrease the generated EMI.
Thermal and current limiting are used to protect the device
from locked rotor conditions. A brake control input forces all
outputs to ground simultaneously to provide dynamic
braking, and an internal voltage sensor does the same when
the supply drops below a predetermined switch point. Power
down braking energy is stored in an external capacitor.
