this is information on a product in full production. july 2014 docid023796 rev 5 1/20 vn5mb02-e smart power driver for motorbike blinker datasheet - production data features ? 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) description the vn5mb02-e is a smart power driver for motorbike blinker; it is connected between the battery positive terminal (v cc 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 (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. type r ds(on) i lsd (typ) v cc vn5mb02-e 0.08 30 a 41 v so-16 narrow ("1($'5 table 1. device summary package order codes tube tape and reel so-16 narrow vn5mb02-e VN5MB02TR-E www.st.com

functional description vn5mb02-e 14/20 docid023796 rev 5 3 functional description 3.1 normal operation when a nominal load is connected to the out pin, the device oscillates by charging the c ext capacitor up to the threshold voltage v ch quickly, and then slowly discharging c ext to the threshold voltage v cl by a constant current i cext . the self oscillating frequency of the device is determined by the relation: n is the internal digital counter (equal to 1066). 3.2 low load condition if the load current is lower than i df , the device will detect the low load at the end of the on phase, and will double the oscillating frequency. 3.3 current protection and thermal limitation the internal current shutdown latches the vn5mb02-e when a heavy overload occurs and, if the overload even is removed, the device may be turned on at the following on time. the thermal limitation reduces the stress on the device if the junction temperature rises (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; when the overload condition is not anymore present, device can be turned on at the following on time. f osc i freq 4nc freq v ch v cl ?
