Product details

Multi-chemistry charger for 2–4 cell packs

It accepts a supply up to 24 V and delivers a constant programmable charging current — the exact current setpoint is defined by external resistors, so the same part can charge a 2-cell Li-ion pack in a handheld instrument or a 4-cell LiFePO4 bank in a field radio. Overcurrent and overvoltage fault protection are built in, which saves a supervisor IC and a sense resistor on the BOM.

ROHS3 compliant. No NRND or last-time-buy notice is in effect. For current pricing and lead time, submit an RFQ — availability is confirmed at quote time through independent distribution.

Frequently asked questions

What is the charging current for MAX17085BETL+T?

The charging current is constant and programmable — set by an external resistor. The exact current value depends on the resistor value chosen; the datasheet provides the formula and typical range.

Is MAX17085BETL+T compatible with 3-cell lithium-ion batteries?

Yes. The part supports 2 to 4 cells, so a 3-cell Li-ion pack (11.1 V nominal) is within its operating range.

Does MAX17085BETL+T have overvoltage protection?

Yes, overvoltage and overcurrent fault protection are both built in.

Where can I buy MAX17085BETL+T?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.
