Extending the Input Voltage Range of PowerPath Circuits for Automotive and Industrial Applications &mdash AN107
PDF, 77 Kb, 档案已发布: Jul 30, 2006
The voltage range of Linear Technology's PowerPath circuits can be easily extended with just a few components, thus allowing them to meet the needs of virtually all applications. This application note presents solutions for circuits that must withstand large negative voltages, a reverse adapter input for example, and circuits that must withstand large positive inputs, such as automotive load-dump.

Application Note 107
July 2006
Extending the Input Voltage Range of PowerPath
Circuits for Automotive and Industrial Applications
Greg Manlove
INTRODUCTION POWER
SUPPLY The voltage range of Linear TechnologyвЂ™s PowerPathВ® circuits can be easily extended with just a few components, thus
allowing them to meet the needs of virtually all applications.
This application note presents solutions for circuits that
must withstand large negative voltages, a reverse adapter
input for example, and circuits that must withstand large
positive inputs, such as automotive load-dump.
EXTENDING THE VOLTAGE RANGE
Any of LinearвЂ™s PowerPath controller circuits can beneп¬Ѓt
from an extended voltage range, even those that already
have wide operating and absolute maximum voltage
ranges. For instance, the LTC4412HV and LTC4414 will
each withstand voltages from вЂ“14V to 40V, which can be
extended further using the techniques described here.
Likewise, the LTC4412вЂ™s range of вЂ“14V to 28V can be
extended. The voltage ranges of monolithic PowerPath
solutions such as the LTC4411, which ranges from вЂ“0.3V
to 6V, can also be extended, though not as far. …

Simple Battery Circuit Extends Power over Ethernet (POE)
Peak Current вЂ“ Design Note 361
Mark Gurries
Introduction
Power over Ethernet (PoE) is a new development that allows for the delivery of power to Ethernet-based devices
via standard Ethernet CAT5 cable, precluding the need
for wall adapters or other external power sources. The
PoE speciп¬Ѓcation deп¬Ѓnes a hardware detection protocol
where Power Sourcing Equipment (PSE) is able to identify
PoE Powered Devices (PDs), thus allowing full backwards
compatibility with non-PoE-aware (legacy) Ethernet devices. The PoE speciп¬Ѓcation also sets an upper limit
on the power that can be drawn by a PD. The problem
is: what happens when a PD must draw more power
than allowed by the PoE standard? Examples may be
the spin up of a disk drive or a period of sustained
transmission of data from an RF transmitter. If the
average power load of these applications is less than

DESIGN FEATURES Monolithic Ideal Diode
Prolongs Battery Life
Introduction Many consumer electronic devices
rely on batteries and wall adapters
for supplying power for portable and
hand held applications. These devices
must rely on some method of automatically and smoothly switching between
the battery and the wall adapter. The
LTC4411 is a low loss ideal diode
that simplifies the implementation of
PowerPathв„ў control circuitry. With
the LTC4411 it is possible to build
an entire power management solution
in a 2mm Г— 3mm footprint.
The LTC4411 is a low-voltage
(2.5V to 5.5V) monolithic (no external P-channel MOSFET needed) ideal
diode. It is pin-compatible with the
LTC4412 ideal diode controller (except
the LTC4411 omits the pin that the
LTC4412 provides to drive the gate
of an external P-channel MOSFET).
The LTC4411 provides a low forward
voltage drop, typically less than 50mV …

DESIGN FEATURES Dual Monolithic Ideal Diodes
Provide a Single-Chip Power
Management Solution
Introduction
The LTC4413 dual monolithic ideal
diode helps reduce the size and improve the performance of handheld
and battery operated devices. It packs
so many features into a tiny package
that it is possible to build an entire
power management solution in a
3mm Г— 3mm footprint. Figure 1 shows
how simple it is to build a complete
battery-wall-adapter PowerPathв„ў
manager.
Despite its compact size, the
LTC4413 includes features that are
necessary in demanding applications,
including thermal management, short
circuit protection, and system-level
power management and control.
Two isolated p-channel MOSFET
transistors serve as low voltage (2.5V
to 5.5V) monolithic ideal diodes. Each …
