ROHM presents most comprehensive
range of Automotive Grade LDO Regulators
AEC-Q100-qualified
devices
provide
superior
characteristics, high reliability and miniaturization
options for a multitude of Automotive applications
ROHM has recently announced the availability of two
new LDO regulator families, complementing the existing
portfolio of LDOs and bringing the total number of its
automotive-grade LDOs up to 184. With its miniaturized
package size, ROHM’s new BUxxJA2MNVX-C series
is the world’s smallest Automotive-grade LDO regulator
whereas the BD7xxLx series provides unmatched
quiescent current features. Customers are now able
to choose from multiple voltage and current options
as well as packaging solutions to meet the exact
requirements of their application, whether in automotive
body, power train and infotainment or advanced driver
assistance systems (ADAS). Both line-ups are based
on ROHM’s vertically integrated product system along
with its proprietary analog design process and package
technologies to achieve high efficiency in a compact form
factor while adding to design flexibility and reliability.
In recent years, Automotive power supply ICs
continue to increase in sophistication and functionality,
accompanied by a greater need for an expanded offering
to cover a wide range of characteristics and application
requirements – such as package type and output current
– instead of simply focusing on an all-in-one-solution.
The BD7xxLx series together with the BD4xxMx series
is optimized for all applications which are connected to
the battery and which require an extreme low quiescent
current. Thanks to its wide input voltage range (up to 50V
max. voltage) and wide operating temperature range
spanning -40° to +125°C, this family is a perfect solution
for automotive body, powertrain and infotainment
systems. The BD7xxLx line-up is composed by 8 part
numbers, with optional output voltage from 3.3V and 5V,
output current capability form 200mA up to 500mA and
3 standard package types.
The proliferation of accident prevention measures and
automated driving systems are demanding advanced
safety systems that deliver higher performance. While
this increases the number of sensors, camera modules
and other mounted components, there is also a need
to decrease part size to improve design flexibility and
reduce vehicle weight. However, so far it has been
difficult to design power supply ICs that deliver high
reliability in a very small form factor. Until now, for
harsh automotive system environments with increased
noise, temperature and vibration, the smallest package
size that could provide the necessary level of reliability
has been 1.5mm2. The new AEC-Q100 qualified
BUxxJA2MNVX-C series provides automotive grade
reliability in an ultra-compact 1mm2 package, decreasing
the mounting area by 55% over existing products. At the
same time, stand-by current consumption (35uA) and
load regulation characteristics (65mV load fluctuation)
are reduced by half, contributing to smaller, higher
performance automotive safety modules. Unlike
conventional products requiring an external capacitance
of at least 1.0uF to prevent oscillation, the new regulator
types support smaller external capacitors as low as
0.22uF for further miniaturization.
New Cypress Automotive LED Driver
Delivers Robust Performance and Minimizes
the Bill-of-Material for Headlight Systems
Cypress Semiconductor Corp. (NASDAQ: CY) today
introduced an automotive LED driver that enables
smaller and more cost-effective headlight systems.
The new S6BL112A automotive-grade LED driver is the
industry’s first to feature synchronous control, which
