Reference Voltage Generator
The current value at 100% is determined by applying voltage at the Vref pin.
The value can be calculated as follows:
Thermal Shutdown Circuit (TSD)
The IC incorporates a thermal shutdown circuit. When the junction temperature (T
transistors are turned off.
Overcurrent Protection Circuit (ISD)
The IC incorporates an overcurrent protection circuit to detect voltage flowing through the output transistors. The
overcurrent threshold is 2.5 A (typ.).

turned on automatically. If an overcurrent occurs again, the same operation is repeated. To prevent false detection due to
glitches, the circuit turns off the transistors only when current exceeding the overcurrent threshold flows for 10 μs or
longer.

configured so that any overcurrent condition will be eliminated as soon as possible.
After 50 μs (typ.), the output transistors are turned on automatically.
The IC has 40°C temperature hysteresis.
Currents flowing through the eight output transistors are monitored individually. If overcurrent is detected in at least
The IC incorporates a timer to count the 50 μs (typ.) for which the transistors are off. After the 50 μs, the transistors are
The target specification for the overcurrent limiter value (overcurrent threshold) is 2.5 A (typ.), and varies in a range
These protection functions are intended only as a temporary means of preventing output short circuits or other
If the guaranteed operating ranges of this product are exceeded, these protection features may not operate and some
The overcurrent protection feature is intended to protect the IC from temporary short circuits only.
Short circuits persisting over long periods may cause excessive stress and damage the IC. Systems should be
