TPS3610U18 描述
The TPS3610 family of supervisory circuits monitors and controls processor activity by providing backup-battery switchover for data retention of CMOS RAM. Other features include an additional power-fail comparator, low-line indication, watchdog function, battery-status indicator, manual switchover, and write protection for CMOS RAM.
The TPS3610 family allow usage of 3-V or 3.6-V lithium batteries as the backup supply in systems with, e.g., VDD = 1.8 V. During power-on, RESET\ is asserted when the supply voltage (VDD or VBAT) becomes higher than 1.1 V. Thereafter, the supply-voltage supervisor monitors VDD and keeps RESET\ output active as long as VDD remains below the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset
