UC3906N Charger IC — Precise, Low-Power Lead-Acid Control

The UC3906N delivers precise control of lead-acid battery charging in three stages: bulk, over-charge, and float. It monitors both voltage and current, using internal logic and a temperature-tracking reference to protect your battery and boost longevity. With a low standby current of just 1.6 mA, the UC3906N stays efficient over time. It supports supply voltages up to 40 V and handles charge currents up to 2 A, in a 16-pin PDIP package. This part fits seamlessly into compact, reliable designs. Explore specifications and download the datasheet to start building with the UC3906N today.
