Product details

34V input, 18V pack — charger for industrial and automotive battery stacks

It accepts a supply input up to 34V, which gives headroom for 24V industrial rails or automotive systems with load-dump transients. The charge current is programmable up to 2A, and a timer termination option is built in — no external microcontroller needed for basic charge management.

Charge profile and chemistry flexibility

Multi-chemistry support means this IC can handle Li-Ion, LiFePO4, or lead-acid chemistries with appropriate resistor divider settings on the output voltage feedback. The constant-current, constant-voltage (CC/CV) profile is standard for Li-Ion; the programmable timer provides a safety backup if the termination current threshold is not reached. The 2A maximum charge current suits 4S or 5S packs.

The package with exposed pad (3.00 mm width) is a surface-mount design.

Lifecycle — active, no LTB watch needed

There is no last-time-buy window, no NRND flag, and no announced end-of-life. The ROHS3 compliance is confirmed.

Frequently asked questions

Is LT3652HVEMSE#PBF equivalent to LT3652HVEMSE?

The LT3652HVEMSE#PBF and LT3652HVEMSE share the same base part number and functional specifications — both are multi-chemistry chargers with 34V input, 18V pack voltage, and 2A charge current. The #PBF suffix indicates ROHS3 compliance (lead-free). The two are electrically equivalent; the #PBF variant is the current ROHS-compliant ordering code.

What are the alternatives to LT3652HVEMSE#PBF?

Within the same LT3652 family, the LT3652HVIMSE#PBF is the closest functional peer — same package, same 4-5 cell support, same 125°C temperature rating, and same programmable features. The LT3652IMSE#PBF and LT3652EDD#PBF are lower-voltage variants (14.4V pack max) for 2-3 cell applications. None are pin-compatible substitutes without checking the feedback divider network.

What is the LT3652HVEMSE#PBF datasheet and pinout?

The full datasheet is available from Analog Devices. The pinout follows the standard 12-lead MSOP-EP / TSSOP-EP arrangement: the exposed pad is the thermal and ground connection. For detailed pin assignments, refer to the manufacturer's datasheet — the pin functions are consistent across the LT3652 family.
