Undervoltage Shutdown & Restart
The BTF50060-1TEA switches OFF whenever V_S drops below V_S(UV)OFF. The device restarts automatically after
the supply voltage increases to a sufficient level (V_S > V_S(UV)ON) and a delay time of t_delay(UV), if the input pin IN is
HIGH. Please see Figure 24 for details. The fault signal is reset if V_S is below V_S(UV) for more than typ. 70µs.
