It delivers a constant programmable charge current up to 25mA, with over-voltage fault protection built in. This part is meant for low-capacity NiMH cells — think small portable instruments, backup memory holders, or wireless sensor nodes that trickle-charge a single cell. The supply maxes out at 5V, so it runs comfortably off a USB port or a 5V rail. ## Package and mounting — field-swap reality It comes in a 6-DFN (2x2 mm) exposed pad package, surface mount. That tiny DFN is not socket-friendly — you need a hot-air station or a reflow oven to swap it. No lab, no bench, let us go: if you are troubleshooting in the field, plan to carry a pre-programmed board or a socket adapter. The exposed pad helps thermal dissipation, which matters if you push the charge current near the 25mA limit in a warm enclosure. ## Lifecycle and sourcing posture It is ROHS3 compliant. No LTB risk for ongoing production.","metaTitle":"LTC4123EDC#TRMPBF NiMH Battery Charger IC, 25mA Max","metaDescription":"Analog Devices LTC4123EDC#TRMPBF is a single-cell NiMH battery charger IC in 6-DFN package.

For higher-current or multi-cell NiMH charging, the LTC4060EFE#TRPBF handles 1 to 4 cells with a higher charge rate, but it is a different package and chemistry range (multi-chem). For single-cell Li-Ion, consider the LTC4124EV#TRMPBF (wireless input) or LTC4065LXEDC-4.1#TRMPBF (wired).
