MAX6740 - Low-Power Dual-/Triple-Voltage SC70 uP Supervisory Circuits

This page provides the datasheet information for the MAX6740, a member of the MAX6736 Low-Power Dual-/Triple-Voltage SC70 uP Supervisory Circuits family.

Description

The MAX6736

MAX6745 are low-power dual-/triplevoltage microprocessor (µP) supervisors.

These devices assert a reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds.

Features

  • are available (see the Selector Guide ). The MAX6736.
  • MAX6745 are offered in a space-saving 5-pin SC70 package and operate over the -40°C to +85°C temperature range. Features o Dual-/Triple-Supply Reset Voltage Monitors o Precision Factory-Set Reset Thresholds for Monitoring from 0.9V to 5.0V o Adjustable Reset Input Down to 0.488V o 150ms and 1200ms (min) Reset Timeout Period Options o VCC1 Power-OK Output for Power-Supply Sequencing.

19-2531; Rev 1; 4/03 Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits General Description The MAX6736–MAX6745 are low-power dual-/triplevoltage microprocessor (µP) supervisors. These devices assert a reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds. The integrated dual/triple supervisory circuits significantly reduce size and power compared to separate ICs or discrete components. The low supply current of 6µA makes these devices ideal for portable equipment. The MAX6736/MAX6737 are dual fixed-voltage µP supervisors with a manual reset input. The MAX6738/ MAX6739 have one fixed and one adjustable reset threshold and a manual reset input.
