Frequently Asked Questions
What is the regulation voltage of the LTC4052EMS8E-4.2#TRPBF and which battery chemistry does it target?
The LTC4052EMS8E-4.2#TRPBF regulates to a fixed 4.2 V end-of-charge voltage, which is the standard termination point for single-cell Lithium-Ion batteries. This fixed voltage simplifies design by removing the need for external voltage-setting resistors. The device supports 1-cell Li-Ion chemistries and integrates overcurrent protection to prevent unsafe charging conditions.
How does the pulse charging method in LTC4052EMS8E-4.2#TRPBF benefit portable device battery longevity?
The pulse charging algorithm applies charge current in controlled bursts rather than continuous current, which reduces heat buildup and stress on the Li-Ion cell. Operating from a single 5 V USB or adapter input, the charger maintains 4.2 V regulation across up to 1 channel. This approach can extend battery cycle life in wearables and hearables that undergo frequent daily charging.
For a space-constrained wearable PCB, what package footprint does the LTC4052EMS8E-4.2#TRPBF occupy?
The LTC4052EMS8E-4.2#TRPBF uses an 8-pin MSOP package (approximately 3 mm × 5 mm footprint), making it suitable for compact portable PCBs where board area is limited. The device integrates overcurrent protection on-chip, so no external sense resistor is needed, further saving 1-2 mm² of additional board space compared to discrete solutions.
Is the LTC4052EMS8E-4.2#TRPBF RoHS compliant and what does the TRPBF suffix indicate?
The TRPBF suffix indicates the device is supplied in tape-and-reel format with a lead-free (Pb-free) finish, complying with RoHS environmental directives. The part is rated for industrial temperature ranges and the e3 JEDEC moisture sensitivity designation confirms compatibility with standard SMT reflow profiles up to 260°C peak.
