Overcurrent Protection Circuit (ISD)
The TB6559FG allows for the sensing of the current that flows through each output transistor.
The currents through each of the output transistors are continually monitored. In the event of an overcurrent
in at least one of the transistors, the overcurrent protection circuitry turns all transistors off.
The overcurrent protection circuitry incorporates a timer to measure 50
μs (typ.) after the transistors are
turned off. After 50
μs, the protection circuitry turns the output transistors back on again automatically. If the
overcurrent persists, the device begins cycling into and out of thermal shutdown. To prevent false detection due
to glitches, the overcurrent protection circuitry turns off the transistors only when the current exceeds the
shutdown threshold for 10
μs or longer.
The design target value for current limiting is 5.0 A (typ.) but has variations between 4.0 to 6.0 A.
