产品概述

The DS1374U-33+ is an I2C, 32bit binary counter watchdog RTC with trickle charger and reset input/output in 10 pin µSOP package. The 32-bit binary counter designed to continuously count time in seconds. An additional counter generates a periodic alarm or serves as a watchdog timer. If disabled, this counter can be used as 3 bytes of non-volatile (NV) RAM. Separate output pins are provided for an interrupt and a square wave at one of four selectable frequencies. A precision temperature-compensated reference and comparator circuit monitor the status of VCC to detect power failures, provide a reset output and automatically switch to the backup supply when necessary. Additionally, the reset pin is monitored as a pushbutton input for externally generating a reset. The device is programmed serially through an I2C serial interface.
  • Supply voltage range is 2.97V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Single pin pushbutton reset input/open-drain reset output
  • Automatic power-fail detect and switch circuitry
  • UL recognized
