Frequently Asked Questions
What is the maximum charge current and float voltage supported by LTC4070EMS8E#TRPBF?
The LTC4070EMS8E#TRPBF supports a maximum charge current of 50 mA and a regulated float voltage of 4.2 V, suitable for single-cell Li-Ion and Li-Polymer batteries. These parameters make it appropriate for small-capacity cells in automotive backup and sensor power applications needing precise charge termination.
Which automotive system designs can integrate LTC4070EMS8E#TRPBF for reliable battery charging?
Automotive designs such as tire pressure monitoring systems (TPMS), remote keyless entry modules, and ECall backup power units can integrate this device. It operates across an automotive-grade temperature range of -40°C to +125°C, ensuring reliable charging performance across harsh under-hood and cabin environments.
How does the adjustable threshold feature of LTC4070EMS8E#TRPBF benefit battery management flexibility?
The adjustable threshold allows designers to set the recharge trigger point and termination voltage for different battery chemistries or capacities using external resistors. This flexibility reduces component count compared to fixed-threshold chargers and lets a single IC accommodate multiple 3.6 V to 4.2 V lithium cell variants in a platform design.
How does the 8-pin MSOP EP package help with thermal management in LTC4070EMS8E#TRPBF designs?
The exposed pad (EP) on the MSOP-8 package provides a low-thermal-resistance path to the PCB ground plane, reducing junction temperature rise during 50 mA charging. This allows the device to sustain rated charge current without external heat sinking, which is critical for compact automotive PCBs with limited airflow.
