The TPS3803-01DCKRG4 is a Single Voltage Detector that provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. In addition to the fixed sense threshold monitored at VDD, the TPS3805 device provides a second adjustable SENSE input. RESET is asserted in case any of the two voltages drops below VIT. During power on, RESET is asserted when supply voltage VDD becomes higher than 0.8V. Thereafter, the supervisory circuit monitors VDD (and/or SENSE) and keeps RESET active as long as VDD or SENSE remains below the threshold voltage VIT. As soon as VDD (SENSE) rises above the threshold voltage VIT, RESET is deasserted again.
● Single voltage detector (adjustable/1.5V)
● High ±1.5% threshold voltage accuracy
● 3µA Typical supply current at VDD = 3.3V
● Open-drain reset output
● Green product and no Sb/Br
●IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
