ANALOG DEVICES ADM691AARUZ 监控器电路, 高电平有效, 低电平有效复位, 4.75V-5.5V输入, TSSOP-16
The ADM691A 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 family of products provides an upgrade for the MAX691A/93A/800M family of products. Power-on reset output function during power-up, power-down and brownout conditions. The circuitry remains operational with VCC as low as 1V. Battery backup switching for CMOS RAM, CMOS microprocessor or other low power logic. A reset pulse if the optional watchdog timer has not been toggled within a specified time.
