Design Once; Use Twice: Monolithic SEPIC/Boost Regulators
with Wide VIN Range Satisfy Requirements of Both Consumer
and Commercial Vehicles
Molly Zhu Automobile manufacturers continually add electronic control units (ECUs) to support
increasing numbers of performance, comfort and safety features. ECU power either
comes from a single lead-acid battery in consumer vehicles, or from two batteries in
commercial vehicles. Ideally, an ECU can run off either, enabling a single design for
both consumer and commercial vehicles. This requires that ECU power ICs support
an input range covering both configurationsвЂ”namely 3.5V to 60V. Furthermore,
the power ICs should feature ultralow quiescent current, preserving the vehicleвЂ™s
battery run time when the engine is off, but always-on systems remain engaged.
The LT8495 and LT8494 are high voltage
switching regulators that meet these
requirements when configured as
SEPIC or boost converters. Both parts
operate over 2.5V to 60V input, and
have low quiescent current to extend
the battery life. The quiescent current
of the LT8495 is 9Вµ A, and is 7Вµ A for the
LT8494. The parts are available in 20-lead
QFN and 20-lead TSSOP packages. supply voltage is monitored by poweron reset, and the software/hardware
activities are supervised by watchdog
timers. These functions are integrated …
