TS836 MICROPOWER VOLTAGE SUPERVISOR RESET ACTIVE HIGH ■ ULTRA LOW POWER CONSUMPTION: 12µA max. at Vcc = 5V ■ PRECISION RESET THRESHOLD (guaranteed over Temperature) ■ THRESHOLD VOLTAGE: 4.50V typ. FOR TS836-4 ■ GUARANTEED RESET OPERATION FOR VCC DOWN TO 1V ■ OPEN DRAIN OUTPUT COMPARATOR WITH Vol = 450mV typ. @ I ol = 8mA & Vcc = 4V ■ FAST RESPONSE TIME: 20µs FOR A 10mV D SO8 (Plastic Micropackage) Z TO92 (Plastic Package) c u d OVERDRIVE ■ 100mV INTERNAL HYSTERESIS DESCRIPTION The TS836 ultra low power integrated circuit incorporates a high stability band-gap voltage reference and a comparator with open drain output. e t le ) s t( o r P P TSSOP8 (Thin Shrink Small Outline Package) o s b O - The threshold voltage is set at 4.5V for TS836-4 by internal thermally matched resistances. The comparator exhibits a 20µs response (with 10mV overdrive) and has an open drain output active when input voltage is lower than the threshold. ) s ( ct An internal hysteresis of 100mV increases the comparator’s noise margin and prevents false reset operation. u d o r P e APPLICATION t e l o ■ Power-on reset generator for micro controller ■ Power failure detector s b O PIN CONNECTIONS (top view) SO8-TSSOP8 NC 8 1 OUT TS836-4I NC 5 2 IN 3 NC 4 GND Package Temperature Range -40, +85°C D Z P • • • Z= TO92 Plastic package - also available in Bulk (Z), Tape & Reel (ZT) and Ammo Pack (AP) D = Small Outline Package (SO) - also available in Tape & Reel (DT) P = Thin Shrink Small Outline Package (TSSOP) - only available in Tape & Reel (PT) May 2003 NC 6 TO92 ORDER CODE Part Number NC 7 1 OUT 2 IN 3 GND 1/10 TS836 ABSOLUTE MAXIMUM RATINGS Symbol VCC Parameter Supply Voltage VOUT Output Voltage IOUT Output Current 1) Unit 7 V -0.3 to Vcc Power Dissipation2) Storage Temperature + V 0.3 20 mA 700 625 625 mW -65 to +150 °C SO8 TSSOP8 TO92 PD TSTG Value 1.
