Heatsinking
The junction temperature of the chip highly effects the lifetime of the circuit. In high-current applications, the
heatsinking must be carefully considered.
The Rth
of the NJM3770A can be reduced by soldering the ground pins to a suitable copper ground plane on
the printed circuit board (see figure 8) or by applying an external heatsink type V7 or V8, see figure 10.
The diagram in figure 15 shows the maximum permissible power dissipation versus the ambient temperature in
°
C, for heatsinks of the type V7, V8, or a 20 cm
2
copper area respectively. Any external heatsink or printed circuit
board copper must be connected to electrical ground.
For motor currents higher than approx 600 mA, some form of heatsinking is recommended to assure optimal
reliability.
The diagrams in figures 14 and 15 can be used to determine the required heatsinking of the circuit. In some
systems, forced-air cooling may be available to reduce the temperature rise of the circuit.
