VN5MB02TR-E

VN5MB02-E Smart Power driver for motorbike blinker Datasheet - production data Description 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. ("1($'5 SO-16 narrow Features Type RDS(on) Ilsd (Typ) VCC VN5MB02-E 0.08 Ω 30 A 41 V 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. • Complete direction indicator in a SMD package • Double frequency flashing in low load conditions 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. • 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) Table 1.
