The LTC4091EDJC#TRPBF is a 36V Li-Ion battery charger and power backup manager from Analog Devices Inc. This integrated circuit features a step-down switching regulator that charges a battery from a primary power source while simultaneously supplying power to the load. In the event of primary power loss, the load is seamlessly transitioned to a backup Li-ion/polymer battery.
Key electrical specifications include a wide input voltage range of 6V to 36V (60V absolute maximum) and a maximum output voltage of 4.45V. The charger provides adaptive output control for high efficiency charging and features a programmable charge current. Users can select between 4.1V or 4.2V battery charge voltages. For backup power, an internal 75mΩ ideal diode connects the battery to the load, with an option for an external ideal diode FET driver to further reduce voltage drop.
The LTC4091EDJC#TRPBF is housed in a thermally enhanced, low-profile 6mm x 3mm 22-lead DFN package. This compact form factor is suitable for space-constrained applications. The device also includes features such as an end-of-charge status output, a termination timer, and an NTC thermistor input for battery temperature monitoring during charging.
Applications for this component include fleet and asset tracking, automotive GPS data loggers, automotive telematics systems, and general battery backup systems where reliable power management is critical.
The input voltage range is 6V to 36V, with an absolute maximum rating of 60V.
The maximum output voltage is 4.45V.
