VN5MB02TR-E

专业电源管理 PMIC Motor bike blinker

The VN5MB02-E is a Smart Power driver for motorbike blinker; it is connected between the battery positive terminal VCCpin 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.
