PBL 3771/1
General
Phase inputs. A logic HIGH on a Phase
input gives positive current flowing out
from MA into MB. A logic LOW gives a
current in the opposite direction.
Slow/fast current decay. A logic HIGH
on the CD input gives slow current
decay, a logic LOW gives fast current
decay.
Heat sinking. Soldering the four center
pins onto a free PCB copper area of 20
cm2 (approx. 1.8" x 1.8", copper foil
thickness = 35 µm) permits the circuit to
operate with a maximum of 320 mA
output current, both channels driving, at
ambient temperatures up to +70°C.
Consult figures 12 and 13 in order to
determine the necessary copper area for
heat sinking if higher currents are
required.
Thermal shutdown. The circuit is
equipped with a thermal shutdown
function that reduces the output current
at chip temperatures above +160°C.
Operating temperature. The max re-
commended operating temperature is
125°C. This gives an estimated lifelength
of about 5 years at continous drive, A
change of ±10° would increase/decrease
the lifelength of the circuit with about 5
years.
