Characteristics
When the IC junction temperature reaches the specified value and the TSD circuit is activated, the internal
reset circuit is activated switching the outputs of both motors to off.
When the temperature is set between 130 (min) to 170°C (max), the TSD circuit operates.
When the TSD circuit is activated, the charge pump is halted, and TROTECT pin outputs V
Even if the TSD circuit is activated and Standby goes H → L → H instantaneously, the IC is not reset until
the IC junction temperature drops −20°C (typ.) below the TSD operating temperature (hysteresis function).
When current exceeding the specified value flows to the output, the internal reset circuit is activated, and the
ISD turns off the output.
Until the Standby signal goes Low to High, the overcurrent protection circuit remains activated.
During ISD, IC turns Standby mode and the charge pump halts.
