    Note:
    1. The resistance of heater can be adjusted as required.
    2. Action time is measured from the point of heater being activated to the point of TCO cutoff completely. 
    3. Operating temperature is the Max temperature which the TCO can not blow when conducting rated current for a long time. 

    Application Note:
    ◎ When the BMS  detect the abnormal behavior of EV battery, the BMS output a signal to activate the MOSFET. Then the heater R1&R2 is power on and heat. The thermal cutoff(TCO1) blow and disconnect the circuit. After that, The TCO2 blow and disconnect the heater, the TCO3 blow at the same time and output a remote signal to BMS.
