- Shunt-based charging topology enabling constant current charging from high-impedance energy sources such as solar panels and energy harvesters
- Compact 8-pin MSOP with exposed pad (EP) providing both space efficiency and improved thermal dissipation for up to 500 mA charge currents
Applications
The LTC4071EMS8E#TRPBF is designed for automotive and industrial battery backup systems where a Li-Ion or Li-Polymer cell must be trickle-charged from a low-power source. Its shunt architecture makes it ideal for energy harvesting applications using solar cells or thermoelectric generators where the source impedance is high. The device is also used in wireless sensor nodes, RTC backup batteries, and automotive key fobs requiring always-on low-current maintenance charging.

Frequently Asked Questions
What battery chemistry is the LTC4071EMS8E#TRPBF designed to charge and what float voltage range is supported?
The LTC4071EMS8E#TRPBF is designed for single-cell Li-Ion and Li-Polymer batteries with an adjustable float voltage typically programmable between 3.9 V and 4.2 V using external resistors. This adjustability accommodates both standard 4.2 V lithium-ion cells and lower-voltage LiFePO4-compatible configurations in automotive and IoT backup power applications.
How does the LTC4071's shunt-based charging topology differ from a conventional CC/CV charger for energy harvesting use?
Unlike conventional CC/CV chargers that regulate source current, the LTC4071 uses a shunt regulator topology where excess current from a high-impedance source such as a 5 V solar panel is shunted to ground once the battery reaches float voltage. This allows charging from sources with output impedances from 10 ohms to several kilohms, making it ideal for micro-watt to milliwatt energy harvesting systems at voltages up to 5.5 V input.
What automotive qualification does the LTC4071EMS8E#TRPBF carry and what temperature range does it cover?
The LTC4071EMS8E variant carries the E-grade automotive qualification indicating operation across -40°C to +125°C, and the device is AEC-Q100 qualified for automotive reliability testing. This temperature range covers under-hood and body electronics environments in passenger cars and commercial vehicles, with a YTEOL of 10 years from introduction.
What package does the LTC4071EMS8E#TRPBF use and how does the exposed pad improve thermal performance?
The LTC4071EMS8E#TRPBF is housed in an 8-pin MSOP with an exposed thermal pad (EP) on the underside of the package. The exposed pad can be soldered directly to a PCB copper pour, reducing junction-to-board thermal resistance by approximately 30% to 50% compared to a standard MSOP-8 without EP, supporting charge currents up to 500 mA in compact automotive PCB designs.
