DTQE5242 - One-Cell Li Battery Protectors

Download the DTQE5242 datasheet PDF. This datasheet also covers the DTQE5242-Din variant, as both devices belong to the same one-cell li battery protectors family and are provided as variant models within a single manufacturer datasheet.

Description

The DTQE5242-XXXX Series are protectors for lithium-ion and lithium polymer rechargeable battery with high accuracy voltage detection.

They can be used for protecting single cell lithium-ion or/and lithium polymer battery packs from overcharge, over-discharge, excess current and short circuit.
