Description
Product Overview
TLV803MDBZR Texas Instruments circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems.
The TLV803, TLV853, and TLV863 are functionally equivalent. The TLV853 and TLV863 provide an alternate pinout of the TLV803. The newer TLV803E device is a pin-to-pin alternative to all of these 3.
During power on, RESET asserts when the supply voltage (VDD) exceeds 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps RESET 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) because to ensure proper system reset. The delay time (td(typ) = 200 ms) starts after VDD exceeds the threshold voltage, VIT. When the supply voltage drops below the VIT threshold voltage, the output is active (low) again. All the devices in this family have a fixed sense-threshold voltage (VIT) set by an internal voltage divider.
The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. These devices are available in a 3-pin SOT-23 package and The TLV803 devices are characterized for operation over a temperature range of –40°C to +125°C.
