Package Type
General Description:
The TC1270 and TC1271 are cost-effective system
supervisor circuits designed to monitor VCC in digital
systems and provide a Reset signal to the host
processor when necessary. A manual Reset input is
provided to override the Reset monitor, and is suitable
for
use
as
a
push-button
Reset.
No
external
components are required.
The Reset output is driven active within 20
μsec (4
μsec for F version) of VCC falling through the Reset
voltage threshold. Reset is maintained active for a min-
imum of 140 msec after VCC rises above the Reset
threshold. The TC1271 has an active-high Reset out-
put while the TC1270 has an active-low RESET output.
The output of the TC1270 is valid down to VCC = 1V.
Both devices are available in a 4-Pin SOT-143 pack-
age.
The TC1270/TC1271 devices are optimized to reject
fast transient glitches on the VCC line. Low supply
current of 7
μA (VCC = 3.3V) makes these devices
suitable for battery powered applications.
