Features: SpecificationsDescriptionThe U6030B has the following features including Delay time range: 3.7 s to 20 h;RC oscillator determines switching characteristics;Relay driver with Z-diode;Low supply current;Load dump protection;RF interference protected;Protection according to ISO/IR7637-1(VDE 0839).
The relay control output of U6030B is an open collector Darlington circuit with an integrated 23-V Z-diode for limitation of the cut-off pulse of the relay coil. The maximum static collector current must not exceed 300 mA and saturation voltage is typically 1.1 V@200 mA.The integrated Z-diode (14V)protects the supply voltage,Vs,therefore, the operation of the IC is possible between 6 V and 16 V, supplied by VBatt.However, it is possible to operate the integrated circuit with a 5 V supply, but it should be free of interference voltages. In this case, Pin 7 is connected to Pin 8 as shown in figure 2b, and the R1C1 circuit is onutted.The 1C supply is protected by Rt, Ct, and an integrated Z-diode, while the inputs are protected by a series resistor, integrated Z-diode and RF capacitor (refer to Figure 6).The relay control output is protected via the integrated 23-V Z-diode in the case of short interference peaks. It is switched to conductive condition for a battery voltage of greater than approx. 40 V in the case of load dump. The output transistor U6030B is dimensioned so that it can withstand the current produced.When the operating voltage is switched on, an internal power-on reset pulse (POR) is generated which sets the logic of the circuits to a defined initial condition. The relay output is disabled.
Parameters of U6030B can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use TEMIC prod}xts for any unintended or unauthorized application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
