Frequently Asked Questions
What regulation modes does the TSM1052 support for lithium battery charging?
The TSM1052 supports both constant voltage (CV) and constant current (CC) regulation modes, which are the two essential phases of lithium battery charging. The CC phase limits charge current to protect the battery, while the CV phase holds output voltage stable at the target level. This dual-mode control is implemented in a single 6-pin SOT-23 IC with minimal external components.
How does the TSM1052 fit into a compact 5 V USB charger design?
In a 5 V USB charger, the TSM1052 acts as the CV/CC feedback controller, regulating output voltage and current through optocoupler or direct feedback paths. Its 6-pin SOT-23 footprint (approximately 2.9 mm x 1.6 mm) saves significant board space compared to multi-function PMIC solutions, allowing a complete charger circuit within a compact 10 mm x 15 mm PCB area.
What is the lead time for TSM1052 procurement and how should engineers plan supply chain schedules?
The TSM1052 has a factory lead time of 16 weeks, which engineers must account for in production planning. For designs with high-volume builds or tight launch schedules, maintaining a safety stock of at least 8 weeks' worth of inventory is advisable. Distributors with in-stock quantities can reduce lead time risk for initial prototype or low-volume production runs.
