The SGM41281 or the SGM41281C integrates a boost for generating up to 70V regulated output, a dual-gains current mirror with a controlled output buffer, which is unique to simplify the multi-channel receiving monitoring sharing design with a MCU with regular resolution ADC. Its precise over current protection and mirror voltage drop compensation further make design tradeoff comfortable between more sensitivity and more robust.
The SGM41281 is available in Green TQFN-3×3-16L package and the SGM41281C is available in Green 12-Bump, 1.2mm × 1.6mm, 0.4mm Pitch WLCSP package. Both operate over an ambient temperature range of -40℃ to +85℃.
