Microprocessor Supervisory Circuits
Industry-Standard, Full-Function µP Supervisor
Viewing:
Overview
- 200ms Power-OK/Reset Timeout Period
- 1µA Standby Current, 30µA Operating Current
- On-Board Gating of Chip-Enable Signals, 10ns max Delay
- MaxCap® or SuperCap Compatible
- Guaranteed Active-Low RESET Assertion to VCC = +1V
- Voltage Monitor for Power-Fail or Low-Battery Warning
- Power-Fail Accuracy Guaranteed to ±2% (MAX800L/M)
- Available in 16-Pin Narrow SO, Plastic DIP, and TSSOP Packages
The MAX691A/MAX693A/MAX800L/MAX800M microprocessor (µP) supervisory circuits are pin-compatible upgrades to the MAX691, MAX693, and MAX695. They improve performance with 30µA supply current, 200ms typ reset active delay on power-up, and 6ns chip-enable propagation delay. Features include write protection of CMOS RAM or EEPROM, separate watchdog outputs, backup-battery switchover, and an active-low RESET output that is valid with VCC down to 1V. The MAX691A/MAX800L have a 4.65V typical reset-threshold voltage, and the MAX693A/MAX800M's reset threshold is 4.4V typical. The MAX800L/MAX800M guarantee power-fail accuracies to ±2%.
