TC1270/TC1271

4-Pin μP Reset Monitors

Features:

Package Type

• Precision V_CCMonitor for 1.8V, 2.7V, 3.0V, 3.3V

and 5.0V Nominal Supplies

4-Pin SOT-143

• Manual Reset Input

• 140 msec Minimum RESET, Reset Output

TC1270

TC1271

• RESET Output Valid to V_CC= 1.0V (TC1270)

• Low 7 μA Supply Current

• V_CCTransient Immunity

TC1270 RESET

TC1271 (Reset)

• Small 4-Pin SOT-143 Package

• No External Components

• Replacement for MAX811/812 and Offers a Lower

Threshold Voltage Option

General Description:

The TC1270 and TC1271 are cost-effective system

supervisor circuits designed to monitor V_CCin 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

Applications:

• Computers

• Embedded Systems

• Battery Powered Equipment

• Critical μP Power Supply Monitoring

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 V_CCfalling through the Reset

voltage threshold. Reset is maintained active for a min-

imum of 140 msec after V_CCrises 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 V_CC= 1V.

Both devices are available in a 4-Pin SOT-143 pack-

age.

Reset V_CCThreshold (V)

The TC1270/TC1271 devices are optimized to reject

fast transient glitches on the V_CCline. Low supply

current of 7 μA (V_CC= 3.3V) makes these devices

suitable for battery powered applications.
