www.ti.com TPS3809L30-EP, TPS3809K33-EP, TPS3809I50-EP 3-PIN SUPPLY VOLTAGE SUPERVISORS SGLS369A – AUGUST 2006 – REVISED NOVEMBER 2006 FEATURES Controlled Baseline – One Assembly Site – One Test Site – One Fabrication Site Extended Temperature Performance of –55°C to 125°C Enhanced Diminishing Manufacturing Sources (DMS) Support Enhanced Product-Change Notification Qualification Pedigree (1) 3-Pin SOT-23 Package Supply Current of 9 µA (Typical) (1) Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits. Precision Supply Voltage Monitor 2.5 V, 3 V, 3.3 V, 5 V Power-On Reset Generator With Fixed Delay Time of 200 ms Pin-for-Pin Compatible With MAX 809 DBV PACKAGE (TOP VIEW) GND 1 3 VDD RESET 2 DESCRIPTION The TPS3809 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps RESET active as long as VDD remains bel...
