• It operates at a control frequency up to 700 kHz, realizing the output rise time of 35 ns and the output fall time of 25 ns.
• Pre-start operating current is as small as 70 µA (typical) so that it is possible to miniaturize the start resistor.
• Output block employs totem pole method. The absolute maximum rating of ±1.0 A (peak) allows the direct drive of power MOSFET.
• Built-in pulse-by-pulse overcurrent protection circuit
• Built-in protection circuit against malfunction at low voltage (on/off: 14.2 V/9.2 V)
• Maximum Duty is 44% (typical)
• Equipped with timer latch function and overvolt.
