Description
µPD166031AT1U is part of Renesas' second generation of intelligent power devices (IPD). They are N-channel high-side switches with a charge pump, voltage-controlled input, diagnostic feedback with proportional load current sense, and embedded protection function. The family includes up to 10 devices depending on the on-state resistance, package, and channel number combination. Scalability: Variety of on-state resistance combined with a standardized package on pin-out gives users high flexibility for unit design depending on the target load. Robustness: Because of the advanced protection method, second-generation intelligent power devices achieve high robustness against long-term and repetitive short circuit conditions.
