FEATURES

DESCRIPTION

The LTC^®4110 is a complete single chip, high efﬁciency,

ﬂyback battery charge and discharge manager with auto-

maticswitchoverbetweentheinputsupplyandthebackup

battery or super capacitor. The IC provides four modes of

operation: battery backup, battery charge, battery calibra-

tion and shutdown. Battery backup and battery charge are

automaticstandalonemodes,whiletheoptionalcalibration

moderequiresaCPUhosttocommunicateoveranSMBus.

During calibration the ﬂyback charger is used in reverse

to discharge the battery with a programmable constant

current into the system load eliminating heat generation.

the SMBus to become GPIOs. User programmable over-

discharge protection is provided. The SHDN pin isolates

the battery to support shipping the product with a charged

battery installed.

Complete Backup Battery Manager for Li-Ion/

Polymer, Lead Acid, NiMH/NiCd Batteries and

Super Capacitors

Charge and Discharge Battery with Voltages Above

and Below the Input Supply Voltage

“No Heat” Battery Calibration Discharge Using

System Load

Automatic Battery Backup with Input Supply

Removal Using PowerPath™ Control

Standalone for Li-Ion/Polymer, SLA, and Supercaps

Optional SMBus/I C Support Allows Battery

Capacity Calibration Operation with Host

Over- and Under-Battery Voltage Protection

Adjustable Battery Float Voltage

Precision Charge Voltage 0.5ꢀ

Programmable Charge/Calibration Current Up to

3A with 3ꢀ Accuracy

Optional Temperature Qualiﬁed Charging

Wide Backup Battery Supply Range: 2.7V to 19V

Wide Input Supply Range: 4.5V to 19V

38-Lead (5mm × 7mm) QFN Package

Multiple LTC4110s can be combined to form a redundant

battery backup system or increase the number of battery

packs to achieve longer backup run times.

The LTC4110 is available in a low proﬁle (0.75mm), 38-pin

5mm × 7mm QFN package. The QFN features an exposed

metal die mount pad for optimum thermal performance.
