The ICs provide a high power density; therefore, careful thermal management is necessary. In order to ensure safe long term operation, the device should not heat up to more than 125°C under normal conditions. In worst case conditions, up to 150°C are safe but might trigger thermal switch off. In most applications, a standstill current reduction to less than 50% of the run current is sensible, because holding torque requirements are often relaxed due to mechanical friction. This will save a lot of energy. The automatic reduction reduces to about 30%.
