General Description
The FM1233E is a supervisor circuit that monitors a microprocessor power supply or other system voltage and issues a reset pulse when a fault condition exists. Several different threshold voltages are offered to accommodate 3V systems with different tolerances.

FEATUREs
■ Precision monitoring of 3.3V and lower voltage microprocessor systems
■ VTH values of 2.88V, 2.72V
■ Automatic restart of microprocessor after power failure
■ 140ms (min) power-on RESET delay (typ.: 256ms)
■ Internal 5kΩ pull-up resistor
■ Other reset choices available: 32 to 128ms
■ Operating Temperature -40°C to +105°C
■ SOT23-3 package
