Frequently Asked Questions
What is the maximum battery charge current supported by TPS650245RHBTG4?
The TPS650245RHBTG4 supports a maximum battery charge current of 1.6 A, suitable for charging single-cell Li-ion or Li-polymer batteries in smartphones and tablets. Its 2-channel architecture allows concurrent management of the charge path and a regulated system output rail, reducing external component count compared to discrete charge controller plus regulator solutions in a 32-pin QFN package.
How does the adjustable threshold feature benefit battery management in TPS650245RHBTG4?
The adjustable threshold in the TPS650245RHBTG4 allows designers to set custom overvoltage and undervoltage detection levels for the battery, tailoring protection behavior to specific Li-ion cell specifications. This flexibility is critical in portable designs where battery capacity, chemistry, and safety margins vary across product lines, enabling the same 32-pin QFN IC to support multiple battery configurations without hardware redesign.
Which portable device categories are best served by TPS650245RHBTG4?
TPS650245RHBTG4 is optimally suited for smartphones, tablets, portable media players, and handheld gaming consoles powered by single-cell Li-ion batteries requiring 1.6 A fast charging. Its integrated PMIC approach combining 2-channel power management in a 32-pin QFN (5 mm × 5 mm) footprint also benefits compact wearables, GPS navigators, and portable medical devices where minimizing PCB area while maintaining reliable power regulation is a primary design constraint.
What package does TPS650245RHBTG4 use and what are the thermal implications?
The TPS650245RHBTG4 is housed in a 32-pin QFN package (JESD-30 code S-PQCC-N32) with a 5 mm × 5 mm body, featuring an exposed thermal pad on the underside that must be soldered to a PCB copper pour for heat dissipation. When operating at 1.6 A charge current, proper thermal via placement beneath the pad is essential to keep junction temperature within the rated range and maintain stable charge regulation performance.
Can TPS650245RHBTG4 replace a discrete charge controller and LDO regulator in a space-constrained design?
Yes, the TPS650245RHBTG4 integrates battery charging at up to 1.6 A with multiple regulated output channels in a single 32-pin QFN, directly replacing the combination of a discrete Li-ion charge controller IC and one or more LDO regulators. This integration reduces the solution footprint by up to 40% compared to discrete implementations, making it attractive for wearables, compact IoT nodes, and tablet reference designs targeting PCB areas below 30 mm × 30 mm.
