The HIP1012A is a HOT SWAP dual supply power distribution controller. It drives two external N-Channel MOSFETs to distribute power while providing load fault isolation. It features soft turn-on, overcurrent protection, and timeout control.
The HIP1012A provides hot‑swap dual power distribution for +5 V and +12 V or +3.3 V and +5 V supplies. It drives external N‑Channel MOSFETs, offers programmable current‑limit thresholds, time‑out control, and fault‑isolation indicators such as PGOOD and over‑current latch signals.
The device includes a built‑in charge pump for the 12 V gate drive, supports selectable voltage‑selection modes, and can be reset by a rising edge on either PWRON pin. Typical applications include RAID systems, hot‑plug components, and general power‑distribution control.
