  1. Hyundai i10 has been a huge success for Hyundai in India. In past one year, Hyundai is one of the few car companies which have observed record sales increase, thanks to Hyundai i10 which has made this happen. After this positive response, Hyundai has also launched i10 with Kappa-Engine of 1.2 L capacity.
  2. . Pin 5 - IRED2 cathode (anode to the power supply). Pin 6 - IRED1 cathode (anode to the power supply). Pin 7 - INT to the microcontroller. Pin 8 - SDA to the microcontroller The power supply for the ASIC (VDD) has a defined range from 2.5 V to 3.6 V. The external connected infrared emitter can also be within this range.

The A5358 is a low-current BiCMOS circuit providing all of
the required features for a photoelectric type smoke detector.

Red 2010

This device can be used with an infrared photoelectric chamber
to sense scattered light from smoke particles. A networking
capability allows as many as 50 units to be interconnected so
that if any unit senses smoke all units will sound an alarm.
Special features are incorporated in the design to facilitate
calibration and testing of the finished detector. The device is
designed for applications that comply with European Standard
A variable-gain photoamplifier can be directly interfaced to
an infrared emitter-detector pair. The amplifier gain levels are
determined by two external capacitors and are internally selected
depending on the operating mode. Low gain is selected during
standby and timer modes. During a local alarm, this low gain
is increased (internally) by approximately 10% to reduce false
triggering. High gain is used during pushbutton test and to
periodically monitor the chamber sensitivity during standby.
The internal oscillator and timing circuitry keep standby power
to a minimum by sensing for smoke for only 100 μs every 10 s.
A special three-stage–speedup sensing scheme is incorporated
to minimize the time to an audible alarm and also to reduce
false triggering. Chamber sensitivity is periodically monitored
and two consecutive cycles of degraded sensitivity are required
The A5358 is supplied in a 16-pin dual in-line plastic package
(suffix A), and for surface mount, a 16-pin SOICW (suffix
LW). The lead (Pb) free versions (suffix –T) have 100% matte-
tin leadframe plating. The devices are rated for continuous
operation over the temperature range of –25°C to 75°C.
