r3116x series 0.8% accuracy, 0.5v operating volt age detector with delay function no.ek-161-091101 cmos voltage detector the r3116x series are cmos-based voltage detector ics with the built-in output delay circuit. the series can operate at low vol tage from 0.5v and the detector threshold can be specified from 0.7v. the detector threshold accuracy as high as 0.8% helps to increase stable operating area coupled with lower voltage. additionally, the high accuracy output delay time at 15% allows easy control of the start-up sequence. in addition to sot-23-5 and sc-82ab packages, a 1mm square dfn(plp)1010-4 package is also available. features ? supply current (i ss1 ) typ. 0.35 a (v dd =-v det +1v, r3116x151x) ? operating voltage range (v dd ) 0.5v to 6.0v (topt=25 c) ? detector threshold range (-v det ) 0.7v to 5.0v (internally fixed) ? output delaytyp. 100ms delay set with a 0.022 f external capacitor ? reset signal "l" ? detector threshold accuracy 0.8% ? temp. coeff. of detector threshold typ. 30ppm/ c ? two output types nch. open drain output and cmos ? packages dfn(plp)1010-4, sc-82ab, sot-23-5 (the above shows specification at topt=25 c. design assurance value at -40 c < = < = c is also available. for details, please refer to the datasheet.) block diagrams r3116xxx1a r3116xxx1c (nch. open drain output) (cmos output) out v dd vref gnd delay circuit c d v dd vref gnd delay circuit c d out selection guides timing chart package quantity per reel part no. dfn(plp)1010-4 10,000 pcs r3116k . xx . 1 . ? . -tr sc-82ab 3,000 pcs r3116q . xx . 1 . ? . -tr-f sot-23-5 3,000 pcs r3116n . xx . 1 . ? . -tr-f . xx . : specify the detector threshold within the range 0.7v ( . 07 . ) to 5.0v ( . 50 . ) in 0.1v steps. . ? . : select the output type from ( . a . ) nch. open drain or ( . c . ) cmos. t d gnd gnd v ddl - v det +v det r3116xxx1a t d r3116xxx1c t phl t phl hysteresis detector threshold release voltage minimum operating voltage pull-up voltage supply voltage (v dd ) output voltage (v out ) hysteresis packages (top view) dfn(plp)1010-4 sc-82ab sot-23-5 2 1 3 4 ? 12 43 13 54 2 1out 2c d 3 gnd 4v dd 1v dd 2 gnd 3c d 4out 1out 2v dd 3 gnd 4 nc 5c d ? ) the tab is substrate level (gnd). applications ? microcontroller and logic circuit reset ? wave shaping circuit ? battery checker ? battery back-up circuit ? window comparator ? power failure detector
r3116x series cmos voltage detector 0.8% accuracy, 0.5v operating voltage detector with delay function the currently available informat ion as of december 2009 is provided in this new product news. ek-161-091101 comparison of voltage detectors r3116x series r3112x series supply current (at released) typ. 0.35 a typ. 0.5 a operating voltage range 0.5v to 6.0v 0.7v to 6.0v detector threshold range 0.7v to 5.0v 0.9v to 5.0v detector threshold accuracy 0.8% 2% output delay typ. 100ms delay set with a 0.022 f external capacitor output delay time accuracy 15% - temp. coeff. of detector threshold typ. 30ppm/ c typ. 100ppm/ c packages dfn(plp)1010-4 (1.0mm 1.0mm) sc-82ab (2.0mm 2.1mm) sot-23-5 (2.9mm 2.8mm) son1612-6 (1.6mm 1.6mm) sc-82ab (2.0mm 2.1mm) sc-88a (2.0mm 2.1mm) sot-23-5 (2.9mm 2.8mm) higher accuracy output delay time what is dfn(plp)1010-4? the high-accuracy output delay time allows easy control of the start-up sequence. the dfn(plp)package is a leadless package using an electroforming sheet in place of lead frame. this extremely compact package features increased power dissipation and conversion to thinner type. the name is representing by a combination of the body size and the number of pins, i.e., dfn(plp)1010-4 stands for the body size of 1.0mm 1.0mm and 4pins. an environment-friendly, leadfree package with gold plated contacts complies with the rohs directive.
