STMicroelectronics unveils new switch for automotive applications
1/15/2013 2:30 PM EST
In the seventh generation of ST's VIPower family, the M0-7 series announced today, 75% of family members are available in a 5 x 4mm package, which is 40% smaller than the smallest competing devices. This allows car electronics designers to save pc-board space and aim for smaller module sizes.
Moreover, various internal design changes increase precision, enhance diagnostic feedback, and improve reliability. Specifically, performance improvements include greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class electromagnetic emission (EMI) performance.
Features of M0-7 series:
-- Precise load-current, voltage and temperature-monitor feedback
-- Integrated sense multiplexer
-- Power-limitation and over-temperature latch-off
-- Bulb / LED mode (quad channel)
-- Flexible fault-reset management
-- Reverse-polarity protection
-- Full on- and off-state diagnostics capability
-- Ultra-low quiescent current
Key role
The intelligent high-side
switch has an important role in the development of advanced
automotive electronics. It combines a power MOSFET as the main
electronically controlled switch, with logic, control and sensing
circuitry in a single package. It is connected between a
microprocessor and loads such as lights, motors, heaters or
valves,
allowing the microprocessor to control the loads in response to
inputs such as dashboard switches or sensors, as well as
information
from the intelligent circuitry in the high-side switch. The
sensors
may be ambient-light sensors, rain sensors, cabin-temperature
sensors, wheel-speed sensors or others depending on the type of
subsystem.
Samples of all family members are available now. The first device to enter production will be the dual-channel VND7020AJ-E, in Q2 2013, priced from $1.10 for orders over 1,000 pieces. The full range of package types available across the new family will include PowerSSO-16, PowerSSO-36, Octapak, and SO-8.

I was always admired how they make this things so smart and the same time so small! These engineers are genius!
