The MC33193 is a new generation industry standard UAA1041 “Flasher”.
It has been developed for enhanced EMI sensitivity, system reliability, and
improved wiring simplification. The MC33193 is pin compatible with the
UAA1041 and UAA1041B in the standard application configuration as
shown in Figure 9, without lamp short circuit detection and using a 20 m
shunt resistor. The MC33193 has a standby mode of operation requiring very
low standby supply current and can be directly connected to the vehicle’s
battery. It includes an RF filter on the Fault detection pin (Pin 7) for EMI
purposes. Fault detection thresholds are reduced relative to those of the
UAA1041, allowing a lower shunt resistance value (20 m
) to be used.
