The document provides information about the U2044B supplier, but does not provide specific product features and characteristics.
The document describes the TEMIC U2044B, an integrated circuit used in relay-controlled automotive flashers. It features two separate outputs to control each side of the vehicle independently using only small control currents. The chip includes a built-in oscillator for flashing frequencies, protection against EMI and reverse polarity, and mechanisms to detect lamp outages by frequency doubling.
The datasheet provides detailed electrical characteristics, pin descriptions, functional block diagrams, and application circuit examples. It specifies parameters such as supply voltage ranges (9V to 18V), output currents up to 300 mA for relay drivers, and operating temperatures from -40°C to +100°C. Package information is provided for both DIP14 and SO14 formats.
| Junction temperature | 150 °C |
|---|---|
| Ambient temperature range | -40 to +100 °C |
| Minimum lamp load | 1 W |
| Supply current (switches open) | < 10 mA |
The minimum lamp load for flasher operation is 1 W.
Lamp outage is indicated by frequency doubling during direction mode.
