Note:
The overheating detector circuits feature hysteresis. After overheating is detected, normal operation is
restored only when the junction temperature falls by the hysteresis amount (10°C typ.) in relation to the
overheating detection temperature.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).

Description of Protector Circuit
(1) Overtemperature Protection
There are four built-in overheating detector circuits, one each for channels 1 and 2; channels 3 and 4;
channels 5 and 6; and channels 7 and 8, respectively. The circuit logic is such that, when any of the four
detectors detects overheating, the circuit turns off the output of both its channels(for example, both
channels 1 and 2).
The overheating detector circuits feature hysteresis. After overheating is detected, normal operation is
restored only when the junction temperature falls by the hysteresis amount (10°C typ.) in relation to the
overheating detection temperature.
(2) Overcurrent Protection
When overcurrent is detected, the overcurrent limiter function limits the output current. Normal operation
is restored when the load current drops below the overcurrent detection value.
