TS3809/3810 Series
Taiwan Semiconductor
Document Number: DS_P0000206

Version: E15
Microprocessor Reset Circuit
GENERAL DESCRIPTION
The TS3809/3810 series are used for microprocessor
(µP) supervisory circuits to monitor the power supplies
in µP and digital systems. They provide excellent circuit
reliability and low cost by eliminating external
components and adjustments when used with +5V,
+3.3V, +3.0V, +2.5V powered circuits.
These circuits perform a single function: they assert a
reset signal whenever the V
CC
supply voltage declines
bel
ow a preset threshold, keeping it asserted for at least
200ms after V
CC
has risen above the reset threshold.
Reset thresholds suitable for operation with a variety of
supply voltages are available. TS3809/3810 series have
push pull outputs. TS3809 series has an active low
RESET output, while the TS3810 has an active high
RESET output The reset comparator is designed to
ignore fast transients on V
CC
, and the outputs are
guaranteed to be in the correct logic state for V
CC
down
to 1.0V. Low supply current makes TS3809/3810 series
ideal for use in portable equipment.
