1/7 ■ ULTRA LOW POWER CONSUMPTION : 12µA max. @ VCC = 5V ■ BOTH ACTIVE HIGH AND ACTIVE LOW OUTPUTS ■ RESET TIMER WITH DISABLE FUNCTION ■ PRECISION RESET THRESHOLD (guaran- teed over Temperature) ■ 4.33V typ. THRESHOLD VOLTAGE ■ GUARANTEED RESET OPERATION DOWN TO 1.5V ■ OPEN DRAIN OUTPUT WITH ■ Vol = 450mV typ.@ Iol = 8mA & VCC = 4V ■ FAST RESPONSE TIME : 20µs FOR A 10mV OVERDRIVE ■ 100mV INTERNAL HYSTERESIS DESCRIPTION The TS834 is a voltage supervisor providing two different outputs (one active low and one active high) with an integrated timer that can be dis- abled. It incorporates a high stability bandgap voltage reference and a comparator with open drain out- put. The threshold voltage is set at 4.33V by internal thermally matched resistors. The comparator exhibits a 20µs response (with 10mV overdrive). An internal hysteresis of 100mV increases the comparator noise margin and prevents false reset operation. APPLICATION ■ Computers ■ Microcontrollers ■ Microprocessor systems ■ Intelligent instruments ■ Power failure detection ORDER CODE D = Small Outline Package (SO) - also available in Tape & Reel (DT) P = Thin Shrink Small Outline Package (TSSOP) - only available in Tape & Reel (PT) PIN CONNECTIONS (top view) Part Number Temperature Range Package D P TS834-5I -40, +85°C • • D SO8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) 1 2 3 4 8 7 6 5 Reset Low Vcc NC Gnd Reset High NC NC Timer Control* * This pin must be connected to Vcc or Gnd TS834 MICROPOWER VOLTAGE SUPERVISOR RESET ACTIVE LOW OR HIGH INTEGRATED TIMER January 2001
