An internal timer delays the • Temperature Range: –40°C to +125°C return of the output to the inactive state (high) to ensure proper system reset. The delay time (td(typ) = • Open-Drain, RESET Output 200 ms) starts after VDD has risen above the threshold voltage, VIT. When the supply voltage drops APPLICATIONS below the VIT threshold voltage, the output becomes • DSPs, Microcontrollers, and Microprocessors active (low) again. All the devices in this family have • Wireless Communication Systems a fixed sense-threshold voltage (VIT) set by an internal voltage divider. • Portable/Battery-Powered Equipment • Programmable Controls The product spectrum is designed for supply voltages • Intelligent Instruments of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available in a 3-pin SOT-23 package. The TLV803 • Industrial Equipment devices are characterized for operation over a • Notebook and Desktop Computers temperature range of –40°C to +125°C. • Automotive Systems DEVICE FAMILY COMPARISON TYPICAL APPLICATION DEVICE FUNCTION TLV803 Open-Drain, RESET Output TLV809 Push-Pull, RESET Output TLV810 Push-Pull, RESET Output 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. 2 All trademarks are the property of their respective owners.
