Dual Output Flasher
U2044B
Description
The integrated circuit U2044B is used in relay controlled
automotive flashers. With two output stages each side of
the vehicle is controlled separately. A left and a right
direction indicator input with only a small control current
makes switch contacts for small loads possible.
The separate hazard warning input simplifies the
construction of the hazard switch. Lamp outage is indi-
cated by frequency doubling during direction mode.
Thanks to the extreme low current consumption U2044B
can be connected to the battery directly.
Features
D Temperature and supply voltage compensated
flashing frequency
D Frequency doubling indicates lamp outage
D Two relay driver outputs with high current-carrying
capacity and low saturation voltage
wD Minimum lamp load for flasher operation: 1 W
D Very low susceptibility to EMI
D Protection according to ISO/TR7637/1 level 4
D Extremly low current consumption < 10 mA
(@switches open)
D Reverse polarity protection
D Three control inputs: left, right and hazard warning
