LTC4088 Demo Board
Analog Devices Inc.Demonstration Circuit 1007 is a high efficiency USB power
manager with PowerPath™ control and Li-Ion/Polymer
battery charger featuring the LTC4088. It includes a synchronous
switching input regulator, a full featured battery
charger and an ideal diode. Designed specifically for USB
applications, the LTC4088’s switching regulator automatically
limits its input current to either 100mA, 500mA or
1A for wall-powered applications via logic control. There
are also 2.5mA and 500μA suspend modes to prevent the
battery from running down when the product is connected
to a suspended USB bus.
The switching input stage provides power to VOUT where
power sharing between the application circuit and the
battery charger is managed. Unlike linear PowerPath
controllers, the LTC4088’s switching input stage can use
nearly all of the 0.5W or 2.5W available from the USB port
with minimal power dissipation. This feature allows the
LTC4088 to provide more power to the application and
battery and eases thermal issues in space constrained
applications.
An ideal diode ensures that the system power is available
from the battery when the input current limit is reached or
if the USB or wall supply is removed. The optional external
P-channel MOSFET supplements the internal ideal diode
by reducing RON and increasing efficiency.
A CHRG LED indicates four possible states of the battery
charger. Charging is indicated when the LED is steady-ON.
Not charging is indicated by a steady-OFF. A NTC fault is
indicated by a slow blinking rate (1.5Hz) and a bad battery
is indicated by a fast blinking rate (6.1Hz).
The LTC4088 is available in the low profile 14-Lead
4mm × 3mm × 0.75mm DFN surface mount package.

LT1511 | 3A Constant Current/Constant Voltage Battery Charger
Analog Devices Inc.The LT1511 current mode PWM battery charger is the simplest, most efficient solution to fast charge modern rechargeable batteries including lithium-ion (Li-Ion), nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd) that require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 3A* DC current (4A peak current). Full-charging current can be programmed by resistors or a DAC to within 5%. With 0.5% reference voltage accuracy, the LT1511 meets the critical constant-voltage charging requirement for Li-Ion cells. A third control loop is provided to regulate the current drawn from the AC adapter. This allows simultaneous operation of the equipment and battery charging without overloading the adapter. Charging current is reduced to keep the adapter current within specified levels. The LT1511 can charge batteries ranging from 1V to 20V. Ground sensing of current is not required and the battery?s negative terminal can be tied directly to ground. A saturating switch running at 200kHz gives high charging efficiency and small inductor size. A blocking diode is not required between the chip and the battery because the chip goes into sleep mode and drains only 3?A when the wall adapter is unplugged.* See LT1510 for 1.5A ChargerApplications Chargers for NiCd, NiMH, Lead-Acid, Lithium Rechargeable Batteries Switching Regulators with Precision Current Limit
