LTC4091

36V Battery Charger and

Power Backup Manager

FEATURES

DESCRIPTION

The LTC^®4091 is a 36V Li-Ion battery charger and power

backup manager. The integrated step-down switching

regulator charges a battery from a primary power source

while providing power to the load. If primary power is lost,

the load is seamlessly transitioned to the backup Li-ion/

polymer battery. To protect sensitive downstream loads,

the maximum output voltage is 4.45V.

Seamless Transition Between Primary Power

Source and Li-Ion Battery

2A High Voltage Step-Down Regulator with

Adaptive Output Control

Internal 75mΩ Ideal Diode Plus Optional External

Ideal Diode Controller Provides Low Loss

PowerPath™ When Primary Supply Not Present

Wide Input Voltage Range: 6V to 36V (60V Abs Max)

The LTC4091 provides an adaptive output that tracks the

battery voltage for high efficiency charging. The charge

current is programmable and an end-of-charge status

output (CHRG) indicates full charge. Also featured is a

termination timer and an NTC thermistor input used to

monitor battery temperature while charging.

4.45V Max Output Voltage

Full Featured Li-Ion Battery Charger

Pin Selectable 4.1V and 4.2V Charge Voltage Options

Thermally Enhanced Low Profile (0.75mm)

6mm × 3mm 22-Lead DFN Package

Duringbackup, aninternal75mΩidealdiodeconnectsthe

battery to the load. An optional external ideal diode FET

driver is available to reduce the voltage drop even further.

4.1V or 4.2V battery charge voltages can be selected.
