MAX6316LUK41CX-T Datasheet

5-Pin µP Supervisory Circuits with Watchdog and Manual Reset


The MAX6316–MAX6322 family of microprocessor (µP) supervisory circuits monitors power supplies and microprocessor activity in digital systems. It offers several combinations of push/pull, open-drain, and bidirectional (such as Motorola 68HC11) reset outputs, along with watchdog and manual reset features.

The Selector Guidebelow lists the specific functions available from each device. These devices are specifically designed to ignore fast negative transients on VCC. Resets are guaranteed valid for VCCdown to 1V.

♦ Small 5-Pin SOT23 Package
♦ Available in 26 Reset Threshold Voltages 2.5V to 5V, in 100mV Increments
♦ Four Reset Timeout Periods
        1ms, 20ms, 140ms, or 1.12sec (min)
♦ Four Watchdog Timeout Periods
       6.3ms, 102ms, 1.6sec, or 25.6sec (typ)
♦ Four Reset Output Stages
  Active-High, Push/Pull
  Active-Low, Push/Pull
  Active-Low, Open-Drain
  Active-Low, Bidirectional
♦ Guaranteed Reset Valid to VCC = 1V
♦ Immune to Short Negative VCC Transients
♦ Low Cost
♦ No External Components
