SS8037/8(G)  
Microprocessor Reset IC  
FEATURES  
DESCRIPTION  
Precision monitoring of +3V, +3.3V, and +5V  
power-supply voltages  
The SS8037/8 are microprocessor (µP) supervisory  
circuits used 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- pow-  
ered circuits.  
Fully specified over temperature  
Available in three output configurations  
Push-pull RESEToutput (SS8037L)  
Push-pull RESET output (SS8037H)  
Open-drain RESEToutput (SS8038L)  
Power-on reset pulse width of 140ms min  
Supply current of 10µA  
These circuits perform a single function: they assert a  
reset signal whenever the VCC supply voltage declines  
below a preset threshold, keeping it asserted for at least  
140ms after VCC has risen above the reset threshold.  
Reset thresholds suitable for operation with a variety of  
supply voltages are available.  
Guaranteed reset valid to V = +1V  
CC  
Power supply transient immunity  
No external components  
SOT23-3 package  
The SS8038L has an open-drain output stage, while the  
SS8037H/L have push-pull outputs. The SS8038L’s  
APPLICATIONS  
Computers  
Controllers  
open-drain RESET output requires a pull-up resistor  
that can be connected to a voltage higher than VCC. The  
SS8037L has an active-low RESET output, while the  
SS8037H has an active-high RESET output. The reset  
comparator is designed to ignore fast transients on VCC,  
and the outputs are guaranteed to be in the correct logic  
state for VCC down to 1V.  
Intelligent instruments  
Critical µP and µC power monitoring  
Portable / battery-powered equipment  
Automotive  
Low supply current makes the SS8037/8 ideal for use  
in portable equipment. They are available in a 3-pin  
SOT23-3 package.  
This device is available with Pb-free lead finish (second-level interconnect) as SS8037G/8038G.
