(4) Thermal shutdown circuit

When the thermal shutdown circuit is activated at the

chip temperature of about 175_C (typical), the outputs

are left OPEN. The temperature difference between the

activation and deactivation settings is about 15_C. When

the thermal shutdown circuit is deactivated, the outputs

revert to the status determined by input mode.

FOperation notes

(1) The quality of these products have been carefully

checked; however, use of the products with applied volt-

ages, operating temperatures, or other parameters that

exceed the absolute maximum rating given may result in

the damage of the IC and the product it is used in. If the

IC is damaged, the short mode and open modes cannot

be specified, so if the IC is to be used in applications

where parameters may exceed the absolute maximum

ratings, then be sure to incorporate fuses, or other physi-

cal safety measures.

(2) GND potential

The potential for pin 1 must be kept lower than the poten-

tials of the other pins regardless of the circumstances.

(3) Input pins

Voltage should never be applied to the input pins when

the VCC voltage is not applied to the IC. Similarly, when

VCC is applied, the voltage on each input pin should be

less than VCC and within the guaranteed range for the

electrical characteristics.

(4) Back-rush voltage

Depending on the ambient conditions, environment, or

motor characteristics, the back-rush voltage may fluctu-

ate. Be sure to confirm that the back-rush voltage will not

adversely affect the operation of the IC.
