Smart Power Driver 16-Pin SOIC N T/R

The VN5MB02-E is a Smart Power driver for motorbike blinker; it is connected between the battery positive terminal (VCC pin) and a mechanical switch to the right or left side. As soon as the series switch connects the OUT pin to the bulbs, the device begins to turn on/off with a 50% duty cycle. External low voltage capacitors are needed for supplying the device (CEXT), for stabilizing the internal voltage regulator output (CREG) and for setting the oscillating frequency (CFREQ). When a low load is detected, output current lower than Idf, flashing frequency is automatically doubled. The internal current shutdown latches the VN5MB02-E when a heavy overload occurs; thermal limitation reduces the stress on the device if the junction temperature raises (for instance when a soft over current event, not triggering the current latch protection, happens). If the overload condition lasts more than a time tfault, the VN5MB02-E is latched. Complete direction indicator in a SMD package Double frequency flashing in low load conditions High accuracy in setting operating frequency and low load detection Maximum current protection with latch Reverse battery protected Cycle by cycle thermal limitation Suitable for load configuration up to 2 x 10 W + 3.4 W Open-load detection for FAST lane change (patent pending)
