Fixed Delay Time of 200 ms During power-on, RESET asserts when the supply • Pin-for-Pin Compatible with MAX803 voltage (VDD) becomes greater than 1.1 V. • Temperature Range: –40°C to +125°C Thereafter, the supervisory circuit monitors VDD and keeps RESET active as long as VDD remains below • Open-Drain, RESET Output the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (high) to APPLICATIONS ensure proper system reset. The delay time (td(typ) = • DSPs, Microcontrollers, and Microprocessors 200 ms) starts after VDD has risen above the threshold voltage, VIT. When the supply voltage drops • Wireless Communication Systems below the VIT threshold voltage, the output becomes • Portable/Battery-Powered Equipment active (low) again. All the devices in this family have • Programmable Controls a fixed sense-threshold voltage (VIT) set by an internal voltage divider. • Intelligent Instruments • Industrial Equipment The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are • Notebook and Desktop Computers available in a 3-pin SOT-23 package. The TLV803 • Automotive Systems devices are characterized for operation over a temperature range of –40°C to +125°C.
