FM1233A  
3-Pin µC Supervisor Circuit  
General Description  
Features  
The FM1233A 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  
areofferedtoaccommodate3Vsystemswithdifferenttolerances.  
I Precision monitoring of 3.3V and lower voltage  
microprocessor systems  
I VTH values of 2.88V, 2.72V  
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 FM1233A is of open-drain active low  
type.  
I Other reset choices available: 32 to 256ms  
I Operating Temperature -40°C to +105°C  
I Monitors external pushbutton override  
I Internal switch debounce circuitry  
I SOT23-3 package  
The FM1233A also can monitor a switch closure on its output,

or a µP. In the case of a switch, the closure will be debounced by  
circuitry internal to the FM1233A.
