MC3397T serial switching transient protection circuit Under the over-voltage condition (≥ 17.5), the positive and negative load protection serial switching transient protection circuit. During the normal operation, it works depending on low dropout serial component. The over-voltage leads to the off-state. When the input voltage has returned to lead state, the operating voltage under this state ranges with 4 ~ 16V. The load current is greater than 75mA and the impulse withstand voltage is ± 125V (100ms). Its maximum input voltage is ± 85V. Besides, it includes current limit and thermal cut-off circuit inside.
