2 TPS-xx TPS4-xx, TPS5-xx TPS6-xx, TPS8-xx SLVS7B AUGUST 999 REVISED FEBRUARY 4 DESCRIPTION The TPSx family of ulralow volage processor supervisory circuis provides circui iniializaion and iming supervision, primarily for DSP and processor-based sysems. During power-on, is assered when he supply volage ( ) becomes higher han.75 V. Thereafer, he supply volage supervisor moniors and keeps oupu acive as long as remains below he hreshold volage (V IT ). An inernal imer delays he reurn of he oupu o he inacive sae (high) o ensure proper sysem rese. The delay ime, d = 8 ms, sars afer has risen above he hreshold volage (V IT ). When he supply volage drops below he hreshold volage (V IT ), he oupu becomes acive (low) again. No exernal componens are required. All he devices of his family have a fixed-sense hreshold volage (V IT ) se by a high precision inernal volage divider. The TPS/5/6/8 devices incorporae a manual rese inpu, MR. A low level a MR causes o become acive. The TPS4 devices do no have he inpu MR, bu include a high-level oupu same as he TPS5 and TPS6 devices. In addiion, he TPS/4/8 have a wachdog imer ha needs o be riggered periodically by a posiive or negaive ransiion a WDI. When he supervising sysem fails o rerigger he wachdog circui wihin he ime-ou inerval ou =.8 s, oupu becomes acive for he ime period ( d ). This even also reiniializes he wachdog imer. The circuis are available in a 5-pin SOT-5 package. The TPSx devices are characerized for operaion over a emperaure range of -4 C o 85 C.
