• Manufacturer Part Number: mlx90711
• Description: Position/movement Sensing Auto-shutoff
• Manufacturer: ETC-unknow

Power down timing
After disconnecting the mains , the chip will reset:
- within typical 0.25sec when the coil is not activated
(iron is heating)
- within typical 2.5sec when the coil is activated (iron
is in ASO)
Relay and led driver options
The relay is driven by a pulsed signal instead of a
continuous
consumption is reduced.
The relay driver performs this feature. There are
four duty cycles available: 14.4%,16%,
31%. During 7.8 ms after the switching time , the
duty cycle is increased. This will give an increased
energy to the relay for a short time at the moment the
relay coil must change the state of the contact. The
switching time starts by applying the control voltage
on the coil of the relay. The values of the duty cycles

for the first 7.8 ms are in the table in brackets. The
switching frequency of relay and led are the same
and are typically 20.48KHz.
The type of relay should be normally closed (NC). A
NC relay is opened by applying the control voltage
on its coil and in this case the module is in Auto
Shut-Off mode.
