FM1233B  
3-Pin µC Supervisor Circuit  
General Description  
Features  
The FM1233B 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 5V systems with different  
tolerances.  
  Precision monitoring of 5V and lower voltage microprocessor  
systems  
  V values of 4.62V, 4.38V and 4.12V  
TH  
  Automatic restart of microprocessor after power failure  
  140ms (min) power-on RESET delay (typ.: 256ms)  
  Internal 5kpull-up resistor  
The device features a precision temperature-compensated volt-  
age reference and comparator. When V falls to the threshold  
CC  
  Other reset choices available: 32 to 128ms  
  Operating Temperature -40°C to +105°C  
  Monitors external pushbutton override  
  Internal switch debounce circuitry  
voltage, a RESET pulse is issued, holding the output in the  
active state. When power rises above V , the reset remains for  
TH  
approximately 250 ms to allow the system clock and other cir-  
cuits to stabilize. The reset output of FM1233B is of open-drain  
active low type.  
  SOT23-3 package  
The FM1233B 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 FM1233B.
