Descrizione

Traduzione AI

The MAX807 microprocessor (µP) supervisory circuit reduces the complexity and number of components needed to monitor power-supply and battery-control functions in µP systems. A 70µA supply current makes the MAX807 ideal for use in portable equipment, while a 2ns chip-enable propagation delay and 250mA output current capability (20mA in battery-backup mode) make it suitable for larger, higher-performance equipment.

Caratteristiche

Traduzione AI
  • 70µA supply current
  • 2ns chip-enable propagation delay
  • 250mA output current capability (20mA in battery-backup mode)
  • Comes in 16-pin DIP, SO, and TSSOP packages
  • µP reset: The active-low RESET output is asserted during power-up, power-down, and brownout conditions, and is guaranteed to be in the correct state for VCC down to 1V
  • Active-high RESET output
  • Manual-reset input
  • Two-stage power-fail warning: A separate low-line comparator compares VCC to a threshold 52mV above the reset threshold. This low-line comparator is more accurate than those in previous µP supervisors
  • Backup-battery switchover for CMOS RAM, real-time clocks, µPs, or other low-power logic
  • Write protection of CMOS RAM or EEPROM
  • 2.275V threshold detector provides for power-fail warning and low-battery detection, or monitors a power supply other than +5V
  • BATT OK status flag indicates that the backup-battery voltage is above +2.275V
  • Watchdog-fault output—asserted if the watchdog input has not been toggled within a preset timeout period
  • Precision 4.675V (MAX807L), 4.425V (MAX807M), or 4.575V (MAX807N) Voltage Monitoring
  • 200ms Power-OK/Reset Time Delay
  • RESET and RESET Outputs
  • Independent Watchdog Timer
  • 1µA Standby Current
  • Power Switching 250mA in VCC Mode 20mA in Battery-Backup Mode
  • On-Board Gating of Chip-Enable Signals; 2ns CE Gate Propagation Delay
  • MaxCap and SuperCap Compatible
  • Voltage Monitor for Power Fail
  • Backup-Battery Monitor
  • Guaranteed RESET Valid to VCC = 1V
  • ±1.5% Low-Line Threshold Accuracy 52mV above Reset Threshold
