device is able to drive LEDs at a high 2.1-MHz switching
frequency, which enables a compact headlight solution
that uses small, inexpensive inductors, reducing physical
size and bill-of-materials costs. The LED drivers combine
with Cypress’s Traveo™ microcontrollers (MCUs) and
power management ICs (PMICs) to provide a best-in-
class automotive front-lighting solution.
Cypress’s S6BL112A Automotive LED driver features
an input voltage range of 4.5-42 V that encompasses
extreme operating conditions such as cold-cranking—
when the automobile engine starter draws an excessive
amount of current due to starting the engine in cold
temperatures - or load dump - a power surge that
occurs when an automobile battery is disconnected
while the alternator is supplying current during engine
operation. The LED driver also facilitates the design of
electrical system safeguards by including System Safety
Functions such as under current detection, over current
and voltage protection, as well as the ability to mask
undesired LED OPEN diagnosis during cold cranking.
Additionally, its synchronous operation eliminates
unstable dimming that can occur when the input voltage
is low. More information on Cypress’s automotive
LED drivers is available at

“With the fast-growing usage of LED lighting systems
in cars and other vehicles, automotive suppliers are
seeking to minimize the component count and cost in
these systems without compromising on reliability or
performance,” said Kiyoe Nagaya, vice president of the
Analog Business Unit at Cypress. “Cypress’s automotive
LED drivers provide a compact, efficient headlight
solution, supported by our complementary automotive
MCUs and PMICs, with robust performance even in
extreme temperatures or when faced with disruptive
electrical noise.”
The S6BL112A is a one-channel 2A output Buck LED
driver that supports both analog and PWM dimming
functions, enabling precise brightness control. Its
switching frequency can be set between 205 kHz and
2.1 MHz, with high output current accuracy of +/-2%.
The device enables slew rate control without an external
filter, limiting Electro Magnetic Interference (EMI)
generation that can harm peripherals.
Product Availability
The new S6BL112A LED driver is currently sampling,
with production expected in the fourth quarter of 2016.
It is available in a 16-pin, thermally-enhanced TSSOP
package.

New automotive actuators from TT
Electronics deliver significant improvements
to next generation haptic accelerator pedalsV
TT Electronics, a global provider of engineered electronics
for performance critical applications, has introduced
new automotive actuators for next-generation of haptic
accelerator pedals. The new TT Electronics actuators
tackle the weak spots of systems currently available
on the market, offering a sub 400 gram total weight, a
significant reduction from the total weight of comparable
pedals.
The TT Electronics haptic pedal actuators enable power-
efficient transmission, consuming less than one watt of
energy with an active actuator when it reaches a pedal
force increase of at least 10 newtons. The pedal force the
