MIC1232  
5V Voltage Supervisor with Manual Reset,  
Watchdog Timer and Dual Reset Outputs  
General Description  
Features  
The MIC1232 is a low-current microprocessor supervisor  
for monitoring 5V systems. The device features logic  
selectable (TOL) reset thresholds of 5% or 10% of 5V; a  
pushbutton reset input (/PBRST); a watchdog timer with  
three-state selectable (TD) timeout periods of 150ms,  
600ms, or 1.2s; a fixed reset timeout period of 250ms  
(min); and active-low open-drain reset (/RST) and active-  
high push-pull reset (RST) outputs. The /RST output  
maintains a valid reset condition for VCC as low as 1.4V.  
• Low-current version of  
DS1232/MAX1232/TC1232/CAT1232  
• Low current: 18µA (typ), 40µA (max)  
• Selectable threshold (TOL): 5% or 10% of 5V  
• Selectable watchdog timer (TD): 150ms, 600ms, 1.2s  
• Power OK/Reset time delay: 250ms (min)  
• Debounced pushbutton reset input (/PBRST)  
• Dual complementary reset outputs  
The MIC1232 asserts a reset condition if the supply  
voltage drops below the reset threshold, the pushbutton  
reset is asserted low, or the watchdog timer does not see  
a high-to-low transition on the watchdog timer input within  
the watchdog timer period. A reset condition is held for the  
reset timeout period of 250ms (min) after the pushbutton  
input is released or after the supply voltage increases  
above the reset threshold voltage.  
– Active-low, open-drain reset output  
– Active-high, push-pull reset output  
• Available in Pb-Free 8-pin SOIC and PDIP packages  
• –40°C to +85°C temperature range  
• Pin-for-Pin compatible with MIC1832/DS1832/CAT1832  
Applications  
The MIC1232 is a drop-in replacement for the DS1232,  
MAX1232, and TC1232. It consumes a low 18µA (typ) of  
supply current, 40µA (max). This is one-tenth the max  
current of the DS1232, and one-quarter the max current of  
the MAX1232 and TC1232. It operates over the –40C to  
+85C temperature range and is available in the Pb-Free  
8-pin SOIC and PDIP packages.
