TS836
MICROPOWER VOLTAGE SUPERVISOR
RESET ACTIVE HIGH
s ULTRA LOW POWER CONSUMPTION: 12µA
max. at V_cc = 5V
s PRECISION RESET THRESHOLD (guaran-
teed over Temperature)
s THRESHOLD VOLTAGE:
4.50V typ. FOR TS836-4
s GUARANTEED RESET OPERATION FOR
VCC DOWN TO 1V
s OPEN DRAIN OUTPUT COMPARATOR
WITH V_ol = 450mV typ. @ I_ol = 8mA & V_cc = 4V
s FAST RESPONSE TIME: 20µs FOR A 10mV
OVERDRIVE
s 100mV INTERNAL HYSTERESIS
DESCRIPTION
The TS836 ultra low power integrated circuit incor-
porates a high stability band-gap voltage refer-
ence and a comparator with open drain output.
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 ac-
tive when input voltage is lower than the threshold.
An internal hysteresis of 100mV increases the
comparator’s noise margin and prevents false re-
set operation.
APPLICATION
s Power-on reset generator for micro controller
s Power failure detector
