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.

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)

Functional description
3.1
Normal operation
When a nominal load is connected to the OUT pin, the device oscillates by charging the
CEXT capacitor up to the threshold voltage Vch quickly, and then slowly discharging CEXT to
the threshold voltage Vcl by a constant current ICEXT.
The self oscillating frequency of the device is determined by the relation:
I freq
f OSC = --------------------------------------------------------------------4 × n × C freq × ( V ch – V cl )
n is the internal digital counter (equal to 1066).
3.2
Low load condition
If the load current is lower than Idf, the device will detect the low load at the end of the ON
phase, and will double the oscillating frequency.
F ( fault ) = f OSC × Kfreq
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 tfault, the VN5MB02-E is latched; when the
overload condition is not anymore present, device can be turned on at the following on time.
