Overview

  • Supports operation at switching frequencies up to 700 kHz and achieves a 35 ns output rise time and a 25 ns output fall time.
  • Extremely low pre-startup current consumption of 70 µA (typical) allows a significantly smaller startup resistor to be used.
  • Totem pole circuit structure adopted in the output block.
  • Output current absolute maximum rating of ±1.0 A (peak) for direct driving of power MOSFET.
  • Pulse-by-pulse overcurrent protection circuit
  • Low voltage malfunction prevention circuit On/off: 14.2 V/9.2 V
  • Timer latch and overvoltage protection functions
  • Package: SONF-8D (0.60)
  • 27 0.10 Seating plane 0.40 -0.05 +0.10
