... If the junction temperature (Tjmax) reaches 175°C, the TSD circuit will operate, and the coil output circuit of the motor will open. There is a temperature hysteresis of approximately 25°C (BD6373GW and BD6873KN Typ.) and 25°C (BD6753KV Typ.). The TSD circuit is designed only to shut off the IC in order to prevent runaway thermal operation not designed to protect the IC or guarantee its operation. The performance of the IC’ ...
