FM1233D  
3-Pin µC Supervisor Circuit  
General Description  
Features  
The FM1233D is a supervisor circuit that monitors a microproces-  
sor power supply or other system voltage and issues a reset pulse  
when a fault condition exists. Several different threshold voltages  
areofferedtoaccommodate5Vsystemswithdifferenttolerances.  
I Precision monitoring of 5V and lower voltage microprocessor  
systems  
I VTH values of 4.62V, 4.38V and 4.12V  
I Automatic restart of microprocessor after power failure  
I 140ms (min) power-on RESET delay  
I Internal 5kpull-up resistor  
The device features a precision temperature-compensated volt-  
age reference and comparator. When VCC falls to the threshold  
voltage, a RESET pulse is issued, holding the output in the active  
state. When power rises above VTH, the reset remains for approxi-  
mately 250 ms to allow the system clock and other circuits to  
stabilize. The reset output of FM1233D is of open-drain active low  
type.  
I Other reset choices available: 32 to 256ms  
I Operating Temperature -40°C to +105°C  
I SOT23-3 package
