!Operation notes
1. A thermal-shutdown circuit (over-temperature protection circuit) is built in to prevent the IC from thermal breakdown.
Use the IC under the thermal loss allowed to the package. In case the IC is left running over the allowable loss, the
junction temperature rises, and the thermal-shutdown circuit works at the junction temperature of 160°C (typ.)
(the outputs of the driver is turned off). When the junction temperature drops to 135°C (typ.), the IC start operating
again.
2. When stand-by control terminal (Pin 1) drops below 0.5V, stand-by mode is established. Make sure that under normal
operating conditions, this pin at 2.0V or above.
3. If VCC (Pin 8) drops below 2.5V (typ.), the driver is turned off. When the voltage exceeds 2.7V (typ.) the driver
returns to its previous state.
