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.

ORDER CODE

Package

Part Number Temperature Range

TS834-5I -40, +85°C

It incorporates a high stability bandgap voltage

reference and a comparator with open drain out-

put.

•

D = Small Outline Package (SO) - also available in Tape & Reel (DT)

P = Thin Shrink Small Outline Package (TSSOP) - only available

in Tape & Reel (PT)

The threshold voltage is set at 4.33V by internal

thermally matched resistors.

PIN CONNECTIONS (top view)

The comparator exhibits a 20µs response (with

10mV overdrive).

An internal hysteresis of 100mV increases the

comparator noise margin and prevents false reset
