Reference Voltage Generator
The current value at 100% is determined by applying voltage at the Vref pin.
The value can be calculated as follows:
IO (100 ) = Vref × 1/10 × 1/RS[A] (X1 = X2 = L)
Thermal Shutdown Circuit (TSD)
The IC incorporates a thermal shutdown circuit. When the junction temperature (Tj) reaches 160°C (typ.), the output
transistors are turned off.
After 50
μs (typ.), the output transistors are turned on automatically.
The IC has 40
°C temperature hysteresis.
TSD = 160°C (target spec)
ΔTSD = 40°C (target spec)
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.).
Currents flowing through the eight output transistors are monitored individually. If overcurrent is detected in at least
one of the transistors, all transistors are turned off.
The IC incorporates a timer to count the 50
μs (typ.) for which the transistors are off. After the 50 μs, the transistors are
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.
The target specification for the overcurrent limiter value (overcurrent threshold) is 2.5 A (typ.), and varies in a range
from approximately 1.5 A to 3.5 A.
These protection functions are intended only as a temporary means of preventing output short circuits or other
abnormal conditions and are not guaranteed to prevent damage to the IC.
If the guaranteed operating ranges of this product are exceeded, these protection features may not operate and some
output short circuits may result in the IC being damaged.
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
configured so that any overcurrent condition will be eliminated as soon as possible.
