They provide • Battery Supply Current of 100 nA (Max) a battery-backup function ideal for applications that • Precision 5-V Supply Voltage Monitor, Other require data retention of CMOS RAM during fault Voltage Options on Request conditions. When the voltage at VDD drops below a • Backup-Battery Voltage Can Exceed V DD preset threshold (VIT), the active low push-pull RESET output asserts, and VOUT switches from VDD • Watchdog Timer With 800-ms Time-Out to 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-Fail or Low-Battery (td) expires. During power on, RESET is asserted Monitoring when the supply voltage (VDD or VBAT) goes higher than 1.1 V. • Battery Freshness Seal (TPS3617 Only) • 8-Pin MSOP Package The PFI and PFO pins are provided if additional voltage monitoring is needed. If the voltage at PFI is • Temperature Range: –40° to +85°C less than 1.15 V, the push-pull PFO pin will assert low. When the voltage at PFI exceeds the threshold voltage, PFO will go high. • Fax Machines These devices also feature a watchdog timer pin • Set-Top Boxes (WDI) that monitors processor activity and asserts • Advanced Voice Mail Systems RESET if the the processor is inactive longer than • Portable Battery Powered Equipment the watchdog timeout period. If the watchdog timer is • Computer Equipment not used, the WDI pin should be left floating. • Advanced Modems The TPS3617 and TPS3618 are available in an 8-pin • Automotive Systems MSOP package and are characterized for operation over a temperature range of –40 °C to +85°C. • Portable Long-Time Monitoring Equipment • Point-of-Sale Equipment Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
