STMicroelectronics Introduces Next-Generation Technology for Smaller,
Smarter Automotive Electronics 
Latest Intelligent High-Side Switches Set New Standards in
Miniaturization and Precision, Leveraging Package Commonality for
Flexibility and Scalability 
GENEVA -- (Marketwire) -- 01/15/13 --   STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the
spectrum of electronics applications and a top supplier of automotive
semiconductors, has revealed the latest generation of its
pace-setting switch ICs for vehicle electronics such as lights and
body modules. The new devices provide enhanced intelligent features,
improve protection and reliability, and are up to 40% smaller than
competing alternatives. 
Pioneered by ST, intelligent high-side switches provide a more
reliable and efficient replacement for conventional relays. For
several generations, ST's VIPower family has offered advantages such
as a common package style for many devices in the range. This allows
tier-one suppliers to build several module variants using the same
basic hardware and software so car makers can address differing
requirements in international markets and offer various model
specifications and options cost-effectively. The common-package
approach has become widely adopted among high-side switch vendors. 
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.  
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. 
Major 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

  
Background to Automotive High-Side Switches
 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. 
By integrating sensing, control and logic circuitry, the intelligent
high-side switch is able to operate reliably with different types of
loads, such as highly inductive loads like motors, or resistive loads
like heaters. Moreover, these intelligent features allow the switch
to perform many functions without intervention from the
microprocessor, which helps engineers simplify software and utilize
processor resources efficiently. Built-in protection against
conditions such as over-voltage, over-temperature and open or short
circuits helps prevent damage to subsystems, modules or wiring, and
allows the switch to restart when safe.  
Since it is specially designed to operate on the high side of the
load, connected directly to the battery voltage, the high-side switch
allows the negative terminal of the load to be connected directly to
the vehicle chassis. This cuts significant cost and weight from the
vehicle by reducing wiring and connectors.
