Описание

The ADM693 series Supervisory Circuit offers complete single chip solutions for power supply monitoring and battery control functions in microprocessor systems. These functions include µP reset, backup battery switchover, watchdog timer, CMOS RAM write protection and power failure warning. The complete family provides a variety of configurations to satisfy most microprocessor system requirements. The ADM690-ADM695 family is fabricated using an advanced epitaxial CMOS process combining low power consumption (5mW), extremely fast chip enable gating (5ns) and high reliability. RESET assertion is guaranteed with VCC as low as 1V. In addition, the power switching circuitry is designed for minimal voltage drop thereby permitting increased output current drive of up to 100mA without the need for an external pass transistor.

• Write protection of CMOS RAM or EEPROM
• Adjustable reset and watchdog timeout periods
• Specified over-temperature
• Precision voltage monitor
• Automatic battery backup power switching
• Extremely fast gating of chip enable signals (5ns)
• Voltage monitor for power-fail
• High current drive (100mA)
• 1.5R Normal and 20R in backup Low switch on-resistance
• 100ms, 1.6s or adjustable Watchdog timer
• 600nA Standby current

5V CMOS I.C. (EAR99)
