During power on, RESET is asserted when the SUPPORTS DEFENSE, AEROSPACE, supply voltage (VDD or VBAT) becomes higher than 1.1 AND MEDICAL APPLICATIONS V. Thereafter, the supply voltage supervisor monitors • Controlled Baseline VDD and keeps RESET output active as long as VDD • One Assembly/Test Site remains below the threshold voltage (VIT). An internal • One Fabrication Site timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay • Available in Military (–55°C/125°C) time starts after VDD has risen above VIT. When the Temperature Range(1) supply voltage drops below VIT, the output becomes • Extended Product Life Cycle active (low) again. • Extended Product-Change Notification The product spectrum is designed for supply voltages • Product Traceability of 3.3 V and 5 V. The TPS3619 and TPS3620 are available in an 8-pin MSOP package and are characterized for operation over a temperature range (1) Additional temperature ranges available - contact factory of –55°C to 125°C. 1 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.
