GENERAL DESCRIPTION
The ADM869x family of supervisory circuits offers complete
single- chip solutions for power supply monitoring and battery
control functions in microprocessor systems. These functions
include microprocessor 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 ADM869x family is fabricated using an advanced epitaxial
CMOS process combining low power consumption (0.7 mW),

extremely fast chip enable gating (3 ns), and high reliability.
RESET assertion is guaranteed with V
addition, the power switching circuitry is designed for minimal
voltage drop thereby permitting increased output current drive
of up to 100 mA without the need of an external pass transistor.
