HIP4011
Three Phase Brushless DC Motor Controller
April 1994
Features
Description
• 3A DC, 5A Peak Output Current
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
three motor windings, regulating the current through an
external current sensing resistor, according to an analog
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.
• 16V Max. Rated Supply Voltage
