ACE345 - Adjustable USB Load Current Switch

Description

The ACE345 is Adjustable USB Load Current Switch Current Limited designed for high-side load switching applications.

The internal current-limiting circuit protects the input supply against large output short circuit current which may cause the supply to fall out of regulation.

Features

  • include thermal shutdown and constant current output characteristics if current exceed its current limit Features.
  • 2.5 to 5.5V input voltage range.
  • Controlled turn-on.
  • 0.15-1.5A adjustable current limit.
  • +/-6% current limit accuracy.
  • 0.1ohm on resistance.
  • Fast current limit response time.
  • Logic Control Shutdown (IQ.

ACE345 Adjustable USB Load Current Switch Description The ACE345 is Adjustable USB Load Current Switch Current Limited designed for high-side load switching applications. The internal current-limiting circuit protects the input supply against large output short circuit current which may cause the supply to fall out of regulation. The current limit threshold is programmed with an external resistor from ISET Pin to ground. The quiescent supply current is typically 150μA, making the device ideal for portable battery-operated equipment. In shutdown mode, the supply current decreases to less than 0.1μA. Additional features include thermal shutdown and constant current output characteristics if current exceed its current limit Features  2.5 to 5.
