Over-temperature and over-voltage fault protection are integrated, so the charger shuts down safely if the die exceeds its thermal limit or the input voltage spikes above the 16V maximum. ## Active production — no end-of-life concern No PCN or EOL notice has been issued for this base product number BQ24109. Sourcing is via RFQ against the BOM quantity; lead time is confirmed at quote time.","metaTitle":"BQ24109RHLT – TI bqSWITCHER Li-Ion Charger IC, 2A, 20-VQFN","metaDescription":"Texas Instruments BQ24109RHLT bqSWITCHER single-cell Li-Ion/Polymer charger IC. 2A max charge current, 16V input max, -40°C to 85°C.
