Product Data Sheet 4114 N/2H7P Transistor requirements: VCE max. >= 12V; Isink max > 5mA; VCEsat < 0,15V Alternatively to the PWM signal the fan can be controlled by an analog control signal of 0...5 V (5 V corresponds to 100 % PWM) It must be ensured that the power supply is "sink-able" and can operate with the internal pull-up resistor. The shown pull-up resistor to the internal reference voltage (+5V) has 10kOhm. 3.

Product Data Sheet 4114 N/2H7P Locked rotor protection Locked rotor current at UN Clock signal at locked rotor Auto restart Iblock approx. 1.300 mA t3 / t4 typical: 1,7 s / 5,5 s After 5 failed start-ups there is an extended timeout of 30 s. When several fans are operated together (in a fan tray) and one fan starts after the other and the starting current is eventually limited, it can happen that the not yet operated fan is driven in reverse by the counter pressure.

Product Data Sheet 4114 N/2H7P 6 Reliability 6.1 General Attention! In order to achieve the specified life time figure, it is necessary to connect an external capacitor. Complexity, connection, components and configuration must be checked at the project. As a basis a capacitor of 220...1000 uF connected to the supply voltage between plus and minus can be used. Max. suggested lead length between fan and capacitor: 300 mm. Life expectancy L10 at TU = 40 °C 57.500 h Life expectancy L10 at TU max. 25.
