The ADM690ANZ is a 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 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.
