<MFT> Preliminary RT8H034C *This is tentative specification. 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 resistance connected to the source of FET, and has a function which makes an output turn on as compared with reference voltage, and turns off FET for a definite period of time. Moreover, it is possible to control output OFF time by the value of resistance and capacitor linked to CT terminal.

APPLICATION CIRCUIT EXAMPLES Oscillator block About 1kΩ Latch circuitry R priority Waveform of operation OFF区間 OFF section OUT端子 CSM端子 CSP端子 threshold voltage:About 3V 閾値：約3V CT端子 If a CSP terminal exceeds the voltage of a CSM terminal, an OUT terminal will output Low, and CT terminal is simultaneously 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. 130710
