Description

For all new designs with TPS3820-xx-Q1, use the TPS3820-xxQPDBVRQ1 part number. The TPS3820-xxQP isfunctionally equivalent and a replacement to the TPS3820xxQ. The TPS3820-xxQDBVRQ1 is notrecommended for new designs (NRND).

The TPS382x-xx-Q1 family of supervisors provide circuitinitialization and timing supervision, primarily for DSP and processor-based systems. During poweron, RESET asserts when the supply voltage VDD becomesgreater than 1.1 V. Thereafter, the supply voltage supervisor monitors VDDand keeps RESET active low as long as VDD remainsbelow the threshold voltage, VIT−. An internal timer delays the return ofthe output to the inactive state (high) to ensure proper system reset. The delay time,td, starts after VDD has risen above the thresholdvoltage VIT−. When the supply voltage drops below the threshold voltageVIT−, the output becomes active (low) again. No external components arerequired. All the devices of this family have a fixed-sense threshold voltage,VIT–, set by an internal voltage divider. The TPS382x-xx-Q1 family alsooffers watchdog time out options of 200 ms (TPS3820-xx-Q1) and 1.6 s (TPS3823/4/8-xx-Q1).
