FM1233A  
3-Pin µC Supervisor Circuit  
General Description  
Features  
The FM1233A is a supervisor circuit that monitors a micropro-  
cessor power supply or other system voltage and issues a reset  
pulse when a fault condition exists. Several different threshold  
voltages are offered to accommodate 3.3V and 3.0V systems  
with different tolerances.  
Precision monitoring of 3.3V and lower voltage  
microprocessor systems  
V values of 3.08V, 2.88V and 2.72V  
TH  
Automatic restart of microprocessor after power failure  
Reset Timeout Period Choice:  
FM1233A features a precision temperature-compensated volt-  
– Options AC and AD: 140ms (min)/256ms (typ)  
– Option ABA: 17ms (min)/32ms (typ)  
age reference and comparator. When V falls to the threshold  
CC  
voltage, a RESET pulse is issued, holding the output in the  
– Available on request: 64ms (typ) and 128ms (typ)  
active state. When power rises above V , the reset remains  
TH  
Internal 5kpull-up resistor  
asserted for a minimum period (t  
) to allow the system clock  
RST  
Operating Temperature -40°C to +105°C  
Monitors external pushbutton override  
Internal switch debounce circuitry  
SOT23-3 package  
and other circuits to stabilize. The reset output of FM1233A is of  
open-drain active low type.  
The FM1233A also can monitor a switch closure on its output,  
enabling it to recognize an external reset from a pushbutton  
switch or a µP. In the case of a switch, the closure will be  
debounced by circuitry internal to the FM1233A.
