A1174 - Ultrasensitive Hall Effect Latch

Description

TheA1174 is a micro-power, Hall-effect latch for use in portable devices that employ rotational detection systems, and have a power supply voltage between 1.65 and 3.5 V.

The device has a single push-pull output structure and requires no external pull-up resistor for reliable operation.

Features

  • Micro-power latch operation.
  • 1.65 to 3.5 V battery operation.
  • Push-pull output eliminates the need for an external pull- up resistor.
  • User configured, internally or externally controlled sample and sleep periods ▫ Floating the two clock pins results in the use of a fixed sampling clock internal to the device ▫ Toggling the clock pins allows the user to control the sampling and sleep times of the device for extreme low power operation.
  • External control of the clock pins.
