MAX6717 - Maxim

MAX6717 Dual/Triple Ultra-Low-Voltage SOT23 uP Supervisory Circuits

The MAX6715–MAX6729 are ultra-low-voltage microprocessor (µP) supervisory circuits designed to monitor two or three system power-supply voltages. These devices assert a system reset if any monitored supply falls below its factorytrimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds. The.

Features

are available (see Selector Guide). Select reset timeout periods from 1.1ms to 1120ms (min) (see Reset Timeout Period Suffix Guide). The MAX6715
  –MAX6729 are available in small 5, 6, and 8-pin SOT23 packages and operate over the -40°C to +85°C temperature range. Features o VCC1 (primary supply) Reset Threshold Voltages from 1.58V to 4.63V o VCC2 (secondary supply) Reset Threshold Voltages from 0.79V to 3.08V o Externally Adjustable RSTIN Threshold for Auxiliary/Triple-Voltage Monitoring (0.62V internal reference) o Watchdog Timer Option 35s (min) Long Startup Period 1.12s (min) Normal Timeout .
