LTC4079

60V, 250mA Linear Charger

with Low Quiescent Current

FEATURES

DESCRIPTION

The LTC^®4079 is a low quiescent current, high voltage linear

charger for most battery chemistry types including Li-Ion/

Wide Input Voltage Range: 2.7V to 60V

Adjustable Battery Voltage: 1.2V to 60V

Adjustable Charge Current: 10mA to 250mA

Polymer, LiFePO , Lead-Acid or NiMH battery stacks up

Low Quiescent Current While Charging: I = 4µA

to 60V. The maximum charge current is adjustable from

10mA to 250mA with an external resistor. The battery

charge voltage is set using an external resistor divider.

Ultralow Battery Drain When Shutdown or Charged:

< 0.01µA

BAT

Auto Recharge

With an integrated power device, current sensing and

reverse current protection, a complete charging solution

using the LTC4079 requires very few external components.

Thermal regulation ensures maximum charge current

up to the specified limit without the risk of overheating.

Charging can be terminated by either C/10 or adjustable

timer.

Input Voltage Regulation for High Impedance Sources

Thermal Regulation Maximizes Output Current with-

out Overheating

Constant Voltage Feedback with 0.5% Accuracy

NTC Thermistor Input for Temperature Qualified

Charging

Adjustable Safety Timer

Charging Status Indication

Thermally Enhanced 10-Lead (3mm × 3mm)

DFN Package

AEC-Q100 Qualified for Automotive Applications

Input voltage regulation reduces charge current when the

input voltage falls to an adjustable level or the battery

voltage, making it well suited for energy harvesting

applications. Other features include temperature qualified

charging, bad battery detection, automatic recharge with

sampled feedback in standby for negligible battery drain,

and an open-drain CHRG status output. The device is

offered in a compact, thermally enhanced 10-lead (3mm

× 3mm) DFN package.

APPLICATIONS

Embedded Automotive and Industrial

Backup Battery Charging from Another Battery
