Datasheet
c) Thermal shutdown (TSD) circuit
The TSD circuit operates when the junction temperature of the driver exceeds the preset temperature (175 ℃
nominal). At this time, the controller forces all driver outputs to high impedance. Since thermal hysteresis is provided
in the TSD circuit, the chip returns to normal operation when the junction temperature falls below the preset
temperature (150 ℃ nominal). Thus, it is a self-resetting circuit.
The TSD circuit is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or
guarantee its operation in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is
activated, and do not operate the IC in an environment where activation of the circuit is assumed.
d) Over current protection (OCP) circuit
To protect this driver IC from ground faults, power supply line faults and load short circuits, the OCP circuit monitors
the output current for the circuit’s monitoring time (10μs, nominal). When the protection circuit detects an over
current, the controller forces all driver outputs to high impedance during the off time (290μs, nominal). The IC returns
to normal operation after the off time period has elapsed (self-returning type). At the two channels type, this circuit
works independently for each channel.
