OUTLINE DRAWING

RT8H034C is composed by NPN transistors,
PNP transistors and resistors.
This product makes external FET turn on in OFF time,
detects drain current on the voltage of the resistanceconnected to the source of FET, and has a function
which makes an output turn on as compared withreference voltage, and turns off FET for a definite periodof time.
Moreover, it is possible to control output OFF time by thevalue of resistance and capacitor linked to CT terminal.

If a CSP terminal exceeds the voltage of a CSM terminal, an OUT terminal will output Low, and CT terminal issimultaneously charged by the damping time constant determined by RCT (resistance for charge), and CCT (capacity).
If CT terminal exceeds a threshold value (about 3V), an output will be set to ON and CT terminal will be discharged.
In a series of above-mentioned operations, it controls so that the OFF section becomes at fixed time.
CNF and RNF is a noise filter. Please connect if needed.
