VN5MB02-E：Motor bike blinker

The VN5MB02-E is a Smart Power driver for motorbike blinker; it is connected between the battery positive terminal (V_CCpin) 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 (C_EXT), for stabilizing the internal voltage regulator output (C_REG) and for setting the oscillating frequency (C_FREQ).

When a low load is detected, output current lower than I_df, 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 t_fault, the VN5MB02-E is latched.

Key Features
