BATTERY-BACKUP SUPERVISOR FOR RAM RETENTION
Supply Currentof40 μA (Max) The TPS3617 and TPS3618 are battery-backup
supervisors that monitor5V supplies. They provide• Battery Supply Currentof 100 nA (Max) battery-backup function ideal for applications that• Precision 5-V Supply Voltage Monitor, Other require data retentionof CMOS RAM during faultVoltage Options on Request conditions. When the voltageat VDD drops belowa• Backup-Battery Voltage Can ExceedVDD preset threshold (VIT), the active low push-pull
RESET output asserts, and VOUT switches from VDD• Watchdog Timer With 800-ms Time-Out VBAT. When VDD rises above the trip threshold,• Power-On Reset Generator With Fixed 100-ms VOUT switches immediately from VBAT to VDD.Reset Delay Time The RESET output remains low until the delay time• Voltage Monitor for Power-Failor Low-Battery (td) expires.
