rent level of the three phase currents, is sug-
gested to connect the sense resistor using two
differents tracks: one for the connection of the
sources of the output DMOS (pins 35, 36, 58,
59) and another one for the sense amplifier input
(pin 37).
The typical application of the L6237 is in HDD
systems where there is the need to park the
Read-Write Heads before the motor braking.
At power supply switch-offthe BRKinput is driven
low (Active Low), so the power output stage is
switched in a high impedance state. The schottky
diode 1N5818 insulates the L6237 from the main
power supply. The spindle motor now, acting as a
three-phasealternator, supplies the Heads voice-
coil motor through integrated diodes that rectifie
the EMFvoltage.
After a delay longer than the
parking time, the lower output DMOS can be
switched-onand the spindlemotor is braked.
